## Description

Multiply `x`

by 2 to the power `k`

.

## Notes

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. The generic type name
gentype is used to indicate that the function can take float,
float2, float3, float4, float8,
or float16 as the type for the arguments. For any specific use of these
function, the actual type has to be the same for all arguments and the return type.

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.
