Standard library header <cmath> - Reference

Synopsis. For each function with at least one parameter of type /* floating-point-type */, an overload for each cv-unqualified floating-point type is provided where all uses of /* floating-point-type */ in the function signature are replaced with that floating-point type.. For each function with at least one parameter of type /* floating-point-type */ other than std::abs, additional overloads ...

fma - C++ Users

Returns x*y+z. The function computes the result without losing precision in any intermediate result. The following macro constants may be defined in an implementation to signal that this function generally provides an efficiency improvement over performing the arithmetic operations in x*y+z (such as when a hardware multiply-add instruction is used):

atan2 - C++ Users

Additional overloads are provided in this header for other combinations of arithmetic types (Type1 and Type2): These overloads effectively cast its arguments to double before calculations, except if at least one of the arguments is of type long double (in which case both are casted to long double instead). This function is also overloaded in <valarray> (see valarray atan2).
