Detailed Description

Defines numeric types used in Vorpaline.

These types names have the form (u)int<size> or float<size>, where the (optional) u denotes an unsigned type, and the size is in bits.

Function Documentation

◆ optimize_number_representation()

template<class T >

void GEO::Numeric::optimize_number_representation ( T & x )

inline

place holder for optimizing internal number representation

there are specializations for expansion_nt, rational_nt

Definition at line 267 of file numeric.h.

◆ ratio_compare() [1/2]

template<>

Sign GEO::Numeric::ratio_compare	(	const expansion_nt &	a_num,
		const expansion_nt &	a_denom,
		const expansion_nt &	b_num,
		const expansion_nt &	b_denom
	)

Compares two rational numbers given as separate numerators and denominators. Specialization for exact_nt.

Parameters

[in]	a_num,a_denom	defines a = `a_num` / `a_denom`
[in]	b_num,b_denom	defines b = `b_num` / `b_denom`

Returns: the sign of a - b
