Detailed Description

Project wide limits for different quantities.

Function Documentation

◆ isInf()

template<typename T >

bool wlimits::isInf ( T value )

Determines if a number is considered as infinity or not.

Note: 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.

Definition at line 101 of file WLimits.h.

Referenced by wtracking::WTrackingUtility::followToNextVoxel(), WMWriteMesh::saveJson(), and WMWriteMesh::saveVTKASCII().

Here is the caller graph for this function:

◆ isNaN()

template<typename T >

bool wlimits::isNaN ( T value )

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

Note: 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.
