This is a Py2.3 implementation of decimal floating point arithmetic based on
|
the General Decimal Arithmetic Specification:
|
|
http://speleotrove.com/decimal/decarith.html
|
|
and IEEE standard 854-1987:
|
|
www.cs.berkeley.edu/~ejr/projects/754/private/drafts/854-1987/dir.html
|
|
Decimal floating point has finite precision with arbitrarily large bounds.
|
|
The purpose of this module is to support arithmetic using familiar
|
"schoolhouse" rules and to avoid some of the tricky representation
|
issues associated with binary floating point. The package is especially
|
useful for financial applications or for contexts where users have
|
expectations that are at odds with binary floating point (for instance,
|
in binary floating point, 1.00 % 0.1 gives 0.09999999999999995 instead
|
of the expected Decimal('0.00') returned by decimal floating point).
|
|
Here are some examples of using the decimal module:
|
|
>>> from decimal import *
|
>>> setcontext(ExtendedContext)
|
>>> Decimal(0)
|
Decimal('0')
|
>>> Decimal('1')
|
Decimal('1')
|

|
Decimal('-0.0123')
|
>>> Decimal(123456)
|
Decimal('123456')
|
>>> Decimal('123.45e12345678901234567890')
|
Decimal('1.2345E+12345678901234567892')
|
>>> Decimal('1.33') + Decimal('1.27')
|
Decimal('2.60')
|
>>> Decimal('12.34') + Decimal('3.87') - Decimal('18.41')
|
Decimal('-2.20')
|
>>> dig = Decimal(1)
|
>>> print dig / Decimal(3)
|
0.333333333
|
>>> getcontext().prec = 18
|
>>> print dig / Decimal(3)
|
0.333333333333333333
|
>>> print dig.sqrt()
|
1
|
>>> print Decimal(3).sqrt()
|
1.73205080756887729
|
>>> print Decimal(3) ** 123
|
4.85192780976896427E+58
|
>>> inf = Decimal(1) / Decimal(0)
|
>>> print inf
|
Infinity
|
>>> neginf = Decimal(-1) / Decimal(0)
|
>>> print neginf

|
>>> print neginf + inf
|

|
>>> print neginf * inf
|

|
>>> print dig / 0
|

|
>>> print dig / 0
|

Used exceptions derive from this.
|
If an exception derives from another exception besides this (such as

Underflow (Inexact, Rounded, Subnormal) that indicates that it is only

anything, though.

handle -- Called when context._raise_error is called and the

trap_enabler is not set. First argument is self, second is the

context. More arguments can be given, those being after
|
the explanation in _raise_error (For example,
|
context._raise_error(NewError, '(-x)!', self._sign) would
|
call NewError().handle(context, self._sign).)
|
|
To define a new exception, it should be sufficient to have it derive
|
from DecimalException.

This occurs and signals clamped if the exponent of a result has been

altered in order to fit the constraints of a specific concrete

representation. This may occur when the exponent of a zero result would
|
be outside the bounds of a representation, or when a large normal
|
number would have an encoded exponent that cannot be represented. In
|
this latter case, the exponent is reduced to fit and the corresponding
|
number of zero digits are appended to the coefficient ("fold-down").

power operation with negative right-hand operand), and the dividend was
|
not zero.

|
|
This occurs and signals inexact whenever the result of an operation is
|
not exact (that is, it needed to be rounded and any discarded digits
|
were non-zero), or if an overflow or underflow condition occurs. The
|
result in all cases is unchanged.
|
|

|
|
This occurs and signals invalid-operation if an invalid context was

detected during an operation. This can occur if contexts are not checked
|
on creation and either the precision exceeds the capability of the
|
underlying concrete representation or an unknown or unsupported rounding
|
was specified. These aspects of the context need only be checked when
|
the values are required to be used. The result is [0,qNaN].

|
|
This occurs and signals rounded whenever the result of an operation is

rounded (that is, some zero or non-zero digits were discarded from the
|
coefficient), or if an overflow or underflow condition occurs. The
|
result in all cases is unchanged.
|
|

|
|
This occurs and signals subnormal whenever the result of a conversion or
|
operation is subnormal (that is, its adjusted exponent is less than
|
Emin, before any rounding). The result in all cases is unchanged.
|
|
The subnormal signal may be tested (or trapped) to determine if a given
|
or operation (or sequence of operations) yielded a subnormal result.

|
|
This occurs and signals overflow if the adjusted exponent of a result
|
(from a conversion or from an operation that is not an attempt to divide
|
by zero), after rounding, would be greater than the largest value that
|
can be handled by the implementation (the value Emax).
|
|
The result depends on the rounding mode:
|
|
For round-half-up and round-half-even (and for round-half-down and
|
round-up, if implemented), the result of the operation is [sign,inf],
|
where sign is the sign of the intermediate result. For round-down, the
|
result is the largest finite number that can be represented in the
|
current precision, with the sign of the intermediate result. For
|
round-ceiling, the result is the same as for round-down if the sign of
|
the intermediate result is 1, or is [0,inf] otherwise. For round-floor,
|
the result is the same as for round-down if the sign of the intermediate
|
result is 0, or is [1,inf] otherwise. In all cases, Inexact and Rounded
|
will also be raised.

|
|
This occurs and signals underflow if a result is inexact and the
|
adjusted exponent of the result would be smaller (more negative) than
|
the smallest value that can be handled by the implementation (the value
|
Emin). That is, the result is both inexact and subnormal.
|
|
The result after an underflow will be a subnormal number rounded, if
|
necessary, so that its exponent is not less than Etiny. This may result
|
in 0 with the sign of the intermediate result and an exponent of Etiny.
|
|
In all cases, Inexact, Rounded, and Subnormal will also be raised.

Given Decimals self and other and an integer p, attempt to

compute an exact result for the power self**other, with p
|
digits of precision. Return None if self**other is not
|
exactly representable in p digits.
|
|
Assumes that elimination of special cases has already been
|
performed: self and other must both be nonspecial; self must
|
be positive and not numerically equal to 1; other must be
|
nonzero. For efficiency, other._exp should not be too large,
|
so that 10**abs(other._exp) is a feasible calculation.i

|
|
With two arguments, compute self**other.
|
|
With three arguments, compute (self**other) % modulo. For the
|
three argument form, the following restrictions on the
|
arguments hold:
|
|
- all three arguments must be integral
|
- other must be nonnegative
|
- either self or other (or both) must be nonzero
|
- modulo must be nonzero and must have at most p digits,
|
where p is the context precision.
|
|
If any of these restrictions is violated the InvalidOperation
|
flag is raised.
|
|
The result of pow(self, other, modulo) is identical to the
|
result that would be obtained by computing (self**other) %
|
modulo with unbounded precision, but is computed more
|
efficiently. It is always exact.

rounding = context._set_rounding(ROUND_UP)

Compares values numerically.
|
|
If the signs of the operands differ, a value representing each operand
|
('-1' if the operand is less than zero, '0' if the operand is zero or
|
negative zero, or '1' if the operand is greater than zero) is used in
|
place of that operand for the comparison instead of the actual
|
operand.
|
|
The comparison is then effected by subtracting the second operand from
|
the first and then returning a value according to the result of the
|
subtraction: '-1' if the result is less than zero, '0' if the result is
|
zero or negative zero, or '1' if the result is greater than zero.

must be integral. The result will be inexact unless b is

integral and the result is finite and can be expressed exactly

in 'precision' digits.
|

With three arguments, compute (a**b) % modulo. For the

three argument form, the following restrictions on the

arguments hold:
|
|
- all three arguments must be integral
|
- b must be nonnegative
|
- at least one of a or b must be nonzero
|
- modulo must be nonzero and have at most 'precision' digits
|

The result of pow(a, b, modulo) is identical to the result

that would be obtained by computing (a**b) % modulo with

unbounded precision, but is computed more efficiently. It is

always exact.

Returns a value equal to 'a' (rounded), having the exponent of 'b'.
|
|
The coefficient of the result is derived from that of the left-hand
|
operand. It may be rounded using the current rounding setting (if the
|
exponent is being increased), multiplied by a positive power of ten (if
|
the exponent is being decreased), or is unchanged (if the exponent is
|
already equal to that of the right-hand operand).
|
|
Unlike other operations, if the length of the coefficient after the
|
quantize operation would be greater than precision then an Invalid
|
operation condition is raised. This guarantees that, unless there is
|
an error condition, the exponent of the result of a quantize is always
|
equal to that of the right-hand operand.
|
|
Also unlike other operations, quantize will never raise Underflow, even
|
if the result is subnormal and inexact.

|
|
spec is a dictionary whose keys should include 'thousands_sep' and
|
'grouping'; typically it's the result of parsing the format
|
specifier using _parse_format_specifier.
|
|
The min_width keyword argument gives the minimum length of the
|
result, which will be padded on the left with zeros if necessary.
|
|
If necessary, the zero padding adds an extra '0' on the left to
|
avoid a leading thousands separator. For example, inserting
|
commas every three digits in '123456', with min_width=8, gives
|
'0,123,456', even though that has length 9.
