# NAME¶

half_divide,_native_divide - Division functions.# ¶

**gentype half_divide(gentype**

*x*

**, gentype**

*y*

**);**

**gentype native_divide(gentype**

*x*

**, gentype**

*y*

**);**

# DESCRIPTION¶

**half_divide**computes

*x*/

*y*. This function is implemented with a minimum of 10-bits of accuracy i.e. an ULP value less than or equal to 8192 ulp.

**native_cos**computes cosine over an implementation-defined range. The maximum error is implementation-defined. The vector versions of the math functions operate component-wise. The description is percomponent. The built-in math functions are not affected by the prevailing rounding mode in the calling environment, and always return the same value as they would if called with the round to nearest even rounding mode. For any specific use of a function, the actual type has to be the same for all arguments and the return type, unless otherwise specified. The functions 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). The accuracy (and in some cases the input range(s)) of these functions is implementation-defined.

**gentype**indicates that the functions can take

**float**,

**float2**,

**float3**,

**float4**,

**float8**or

**float16**as the type for the arguments.
