Detailed Description

Normal arithmetic operators.

The class arithmetic operators are implemented in terms of these operators. They use GncRational operators internally then call the GncNumeric(GncRational&) constructor which will silently round half-down to obtain int64_t members.

These operators can throw std::overflow_error, std::underflow_error, or std::invalid argument as indicated in the class GncNumeric documentation.

Parameters

a	The right-side operand
b	The left-side operand

Returns

A GncNumeric computed from the operation.
