Fraction(ZeroByZeroPolicy p)
Definition: fraction.h:30
til::fraction
boost::enable_if_c<!std::numeric_limits< T >::is_integer, T >::type fraction(T nom, T denom)
Divides one number by another.
til
Belongs to package Box Do not include directly, include til/Box.h instead.
Definition: Accumulator.h:10
fraction_policies.h
til::Fraction
A class to divide one number by another.
Definition: fraction.h:26
til::Fraction::operator()
T operator()(T nom, T denom)
Returns nom / denom. The 0/0 case is handled by the policy.
