Function Documentation

◆ imath_float_to_half()

static 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()

static float imath_half_to_float ( imath_half_bits_t h)
inlinestatic

Convert half to float

◆ operator<<()

OPENVDB_API std::ostream & operator<< ( std::ostream & os,
half h )

Output h to os, formatted as a float.

◆ operator>>()

OPENVDB_API std::istream & operator>> ( std::istream & is,
half & h )

Input h from is.

◆ printBits() [1/4]

OPENVDB_API void printBits ( char c[19],
half h )

◆ printBits() [2/4]

OPENVDB_API void printBits ( char c[35],
float f )

◆ printBits() [3/4]

OPENVDB_API void printBits ( std::ostream & os,
float f )

◆ printBits() [4/4]

OPENVDB_API void printBits ( std::ostream & os,
half h )
