Detailed Description

Mathematical functions and types.

Function Documentation

abs()

template<typename T >

constexpr T arg_router::math::abs ( T  value )

constexprnoexcept

Returns the absolute value of the integer value.

This only exists because std::abs(T) is not constexpr.

Template Parameters

T	Integral type

Parameters

value

Input

Returns

Absolute value

Definition at line 20 of file math.hpp.

num_digits()

template<typename T >

constexpr T arg_router::math::num_digits ( T  value )

constexprnoexcept

Returns the number of digits in value.

Basicaly log10(value)+1 but constexpr.

Template Parameters

T	Integral type

Parameters

value

Input

Returns

Number of digits.

Definition at line 38 of file math.hpp.

pow()

template<auto Base, typename T >

constexpr T arg_router::math::pow ( T  exp )

constexprnoexcept

Power function.

This only exists because std::power(T) is not constexpr.

Template Parameters

Base	Power base
T	Integral type

Parameters

exp

Exponent

Returns

Base raised to the power exp
