Detailed Description

template<typename BaseType, typename IntermediateType, unsigned int FractionBits>
class fpm::fixed< BaseType, IntermediateType, FractionBits >

Fixed-point number type

Template Parameters

BaseType	the base integer type used to store the fixed-point number. This can be a signed or unsigned type.
IntermediateType	the integer type used to store intermediate results during calculations.
FractionBits	the number of bits of the BaseType used to store the fraction
