Function Documentation

template<typename T >

bool wlimits::isinf

(

T

value

)

Determines if a number is considered as infinity or not.

Notes:

The reason for using here a wrapper to cmath's isinf is that it is only included in C99 which is not part of any existing C++ standard yet.

Parameters:

value

The value to be checked

Returns:

True if the value is infinity, false otherwise.

template<typename T >

bool wlimits::isnan

(

T

value

)

Determines if a number is considered as NaN (aka Not a Number) or not.

Notes:

The reason for using here a wrapper to cmath's isnan is that it is only included in C99 which is not part of any existing C++ standard yet.

Parameters:

value

The value to be checked

Returns:

True if the value is a NaN, false otherwise.
