Numeric.Decimal.Operation

Description

Eventually most or all of the arithmetic operations described in the General Decimal Arithmetic Specification will be provided here. For now, the operations are mostly limited to those exposed through various class methods.

It is not usually necessary to import this module.

Synopsis

Documentation

abs :: (Precision p, Rounding r) => Number p r -> Number p r Source #

If the operand is negative, the result is the same as using the minus operation on the operand. Otherwise, the result is the same as using the plus operation on the operand.

add :: (Precision p, Rounding r) => Number p r -> Number p r -> Number p r Source #

Add two operands.

subtract :: (Precision p, Rounding r) => Number p r -> Number p r -> Number p r Source #

Subtract the second operand from the first.

multiply :: (Precision p, Rounding r) => Number p r -> Number p r -> Number p r Source #

Multiply two operands.

divide :: (FinitePrecision p, Rounding r) => Number p r -> Number p r -> Number p r Source #

Divide the first dividend operand by the second divisor using long division.

plus :: (Precision p, Rounding r) => Number p r -> Number p r Source #

Unary plus

minus :: (Precision p, Rounding r) => Number p r -> Number p r Source #

Unary minus (negation)

compare :: (Precision p, Rounding r) => Number p r -> Number p r -> Number p r Source #

Compare the values of two operands numerically, returning -1 if the first is less than the second, 0 if they are equal, or 1 if the first is greater than the second.
