The table below describes the list of built-in math functions that are defined with the half_ or native_ prefix

(half | native)_ cos	(half | native)_ divide	(half | native)_ exp	(half | native)_ exp2
(half | native)_exp10	(half | native)_ log	(half | native)_ log2	(half | native)_ log10
(half | native)_ powr	(half | native)_ recip	(half | native)_ rsqrt	(half | native)_ sin

Description

mathFunctionsInc.adoc

The math functions that are defined with the half_ prefix are implemented with a minimum of 10-bits of accuracy i.e. an ULP value ⇐ 8192 ulp.

The math functions that are defined with the native_ prefix may map to one or more native device instructions and will typically have better performance compared to the corresponding functions (without the native_ prefix) described. The accuracy (and in some cases the input range(s)) of these functions is implementation-defined.
