    <math> and <cmath>

    Is there a difference between <math> and <cmath>?

    Thanks

    Yes.

    The latter is a C++ header file for accessing the functions in the mathematics library.

    The former does not exist.
    System: Debian Sid and FreeBSD 7.0. Both with GCC 4.3.

    Assuming the OP meant to compare <math.h> and <cmath>, the thread below talks about the difference between <xxxx.h> and <cxxxx>. Basically, in C++ you should use the latter version and qualify the appropriate symbols with std::.
