Standard C++ Library Reference ISO/IEC (VERSION3)

<cmath>

Include the standard header <cmath> to define the macros traditionally defined in the Standard

C library header <math.h>. Including this header also ensures that the names declared with

external linkage in the Standard C library header are declared in the std namespace. In this

implementation, the names may or may not also be declared in the global namespace,

depending on the specific translation environment.

#if <TRADITIONAL C HEADERS>
