// \brief Templated version of the C math library.
// \date 23 Feb 2000
// [26.5.6] In addition to the signatures from the C header
// <math.h>, the C++ header <cmath> adds certain overloaded
// forms of the usual double-precision functions.
// The following signatures should be available for float,
// double and long double :
//
// \code
// T abs(T );
// T acos(T );
// T asin(T );
// T atan(T );
// T atan2(T, T );
// T ceil(T );
// T cos(T );
// T cosh(T );
// T exp(T );
// T fabs(T );
// T floor(T );
// T fmod(T, T);
// T frexp(T, int *);
// T ldexp(T, int);
// T log(T );
// T log10(T );
// T modf(T, T *);
// T pow(T, T );
// T pow(T, int );
// T sin(T );
// T sinh(T );
// T sqrt(T );
// T tan(T );
// T tanh(T );
// \endcode
