B.3 half_ and native_ math functions

List of half_ and native_ math functions. The half_ and native_ variants of the math functions are provided for portability.

Table B-2 half_ and native_ math functions

half_ functions		native_ functions
`half_cos()`		`native_cos()`
`half_divide()`		`native_divide()`
`half_exp()`		`native_exp()`
`half_exp2()`		`native_exp2()`
`half_exp10()`		`native_exp10()`
`half_log()`		`native_log()`
`half_log2()`		`native_log2()`
`half_log10()`		`native_log10()`
`half_powr()`		`native_powr()`
`half_recip()`		`native_recip()`
`half_rsqrt()`		`native_rsqrt()`
`half_sin()`		`native_sin()`
`half_sqrt()`		`native_sqrt()`
`half_tan()`		`native_tan()`

Mali™ GPUs implement most of the full precision variants of the half_ and native_ math functions at full speed so you are not required to use the half_ and native_ functions.

Note:

On Mali GPUs, the following functions are faster than the full precision versions:

native_sin().
native_cos().
native_tan().
native_divide().
native_exp().
native_sqrt().
half_sqrt().
