C run-time library (msvcrt.dll) contains many useful functions. You can find reference in MSDN library.
Several examples:
To calculate floating-point remainder, use function fmod.
Example: double rem=fmod(x y) .
To calculate x raised to the power of y, use function pow.
Example: double pw=pow(x y) .
To calculate x square root, use function sqrt.
Example: double sq=sqrt(x) .
Before using dll functions, they must be declared. For example, if function in MSDN library is given as:
double fmod(
double x,
double y
);
then QM declaration would be:
dll msvcrt ^fmod ^x ^y
QM declares several math functions from C run-time library. They are added to math category.
