===Notes===
All functions added to the C library by this extension are only declared if a macro {{c|__STDC_WANT_IEC_60559_FUNCS_EXT__}} is defined before math.h is included.

The decimal floating-point variants of every function are only defined if {{c|__STDC_WANT_IEC_60559_DFP_EXT__}} is also defined before math.h is included.

The extended precision variants of every function are only defined if {{c|__STDC_WANT_IEC_60559_TYPES_EXT__}} is defined before math.h is included.

The correctly-rounded versions of all functions (with the {{c|cr-}} prefix) are optional.
