DESCRIPTION
sin
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 216... +216.
native_sin computes sine over an implementationdefined range. The maximum error is implementationdefined.
NOTES
The vector versions of the math functions operate componentwise. The description is percomponent.
The builtin 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 builtin 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(3clc), generic type name gentype may indicate half and half{234816} 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 10bits 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 implementationdefined.
