`sin`

computes the sine.

`sincos`

computes sine and cosine of `x`

. The
computed sine is the return value and computed cosine is returned in
`cosval`

.

`sinh`

computes the hyperbolic sine.

`sinpi`

computes `sin`

(`pi * x`

).

`half_sin`

computes sine. `x`

must be in the
range -2^{16}... +2^{16}.

`native_sin`

computes sine over an implementation-defined range. The
maximum error is implementation-defined.

The vector versions of the math functions operate component-wise. The description is per-component.

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.

The built-in math functions take scalar or vector arguments. For any specific use of these function, the actual type has to be the same for all arguments and the return type unless otherwise specified.

The generic type name gentype is used to indicate that the function can take float, float2, float3, float4, float8, float16, double, double2, double3, double4, double8, or double16 as the type for the arguments.

If extended with cl_khr_fp16, generic type name gentype may indicate half and half{2|3|4|8|16} as arguments and return values.

The generic type name gentypef is used to indicate that the function can take float, float2, float3, float4, float8, or float16 as the type for the arguments.

The generic type name gentyped is used to indicate that the function can take double, double2, double3, double4, double8, or double16 as the type for the arguments.

Functions with the `half_`

prefix are implemented with a minimum
of 10-bits of accuracy i.e. an ULP value ≤ 8192 ulp.

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.
