Sine functions.
gentype asin(gentype)
gentype asinh(gentype)
gentype asinpi(gentype x)
Description
asin
is the arc sine function.
asinh
is the inverse hyperbolic sine function.
asinpi
computes asin
(x
) / π.
Notes
General information about builtin math functions: The builtin math functions are categorized into the following:

A list of builtin functions that have scalar or vector argument versions, and,

A list of builtin functions that only take scalar float arguments.
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
, 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.
