Function Documentation

operator""_h()

half half_float::literal::operator""_h ( long double value )

inline

Half literal.

While this returns a properly rounded half-precision value, half literals can unfortunately not be constant expressions due to rather involved conversions. So don't expect this to be a literal literal without involving conversion operations at runtime. It is a convenience feature, not a performance optimization.

Parameters

value

literal value

Returns

half with of given value (possibly rounded)

Exceptions

FE_OVERFLOW,...UNDERFLOW,...INEXACT

according to rounding
