Here is the relevant excerpt from the documentation: > Floating-point formats are assumed to be IEEE-754 binary32 format for > float and IEEE-754 binary64 for double. > > Supported long double formats: IEEE-754 binary64 (ld64) and x86 80 bit > extended precision format (ld80) are fully supported and there is > partial support for IEEE-754 binary128 (ld128).
