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
(half | native)_ sqrt | (half | native)_ tan

## Description

&mathFunctionsInc;

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.
