abs()

template<class T >

constexpr T nonstd::abs ( T  x )

constexprnoexcept

abs(x) returns |x| using -x if x < 0 or x otherwise

Reason to re-implement: std::abs(x) is not officially constexpr

Parameters

[in]

x

Any real value type

Returns

|x|

isdigit()

constexpr int nonstd::isdigit ( int  ch )

constexprnoexcept

Checks if the given character in 0123456789.

Reason to re-implement: std::isdigit(ch) is not officially constexpr

The int-interface is kept from the standard

Parameters

[in]

ch

A character

Returns

int from a simple boolean.

isnan() [1/3]

constexpr bool nonstd::isnan ( double  d )

constexprnoexcept

Checks if the given value is nan

Reason to re-implement: std::isnan(d) is not officially constexpr

Only the three basic interfaces are implemented

Parameters

[in]

d

A value

Returns

int from a simple boolean.

isnan() [2/3]

constexpr bool nonstd::isnan ( float  d )

isnan() [3/3]

constexpr bool nonstd::isnan ( long double  d )

constexprnoexcept

isspace()

constexpr int nonstd::isspace ( int  ch )

constexprnoexcept

Returns 1 if x is a standard space-character.

Reason to re-implement: std::isspace(ch) is not officially constexpr

The int-interface is kept from the standard

Parameters

[in]

x

a character

Returns

1 if x is a space
