NAME

       ldexp - Multiply x by 2 to the power k.

       floatn ldexp(floatn x, intn k);

       floatn ldexp(floatn x, int k);

       float ldexp(float x, int k);

       doublen ldexp(doublen x, intn k);

       doublen ldexp(doublen x, int k);

       double ldexp(double x, int n);

       halfn ldexp(halfn x, intn k);

       halfn ldexp(halfn x, int k);

       half ldexp(half x, int k);

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(3clc), generic type name gentype may indicate half and half{2|3|4|8|16} as
       arguments and return values.
