half

typedef imath_half_bits_t half

if we're in a C-only context, alias the half bits type to half

imath_half_bits_t

typedef uint16_t imath_half_bits_t

a type for both C-only programs and C++ to use the same utilities

imath_half_uif_t

typedef union openvdb::v13_0::math::internal::imath_half_uif imath_half_uif_t

a type for both C-only programs and C++ to use the same utilities

Function Documentation

imath_float_to_half()

imath_half_bits_t imath_float_to_half ( float f )

inlinestatic

Convert half to float

Note: This only supports the "round to even" rounding mode, which was the only mode supported by the original OpenEXR library

imath_half_to_float()

float imath_half_to_float ( imath_half_bits_t h )

inlinestatic

Convert half to float
