NAME
ldexp - returns x times 2 rained to n
SYNOPSIS
float ldexp(float x, float n); float1 ldexp(float1 x, float1 n); float2 ldexp(float2 x, float2 n); float3 ldexp(float3 x, float3 n); float4 ldexp(float4 x, float4 n); half ldexp(half x, half n); half1 ldexp(half1 x, half1 n); half2 ldexp(half2 x, half2 n); half3 ldexp(half3 x, half3 n); half4 ldexp(half4 x, half4 n); fixed ldexp(fixed x, fixed n); fixed1 ldexp(fixed1 x, fixed1 n); fixed2 ldexp(fixed2 x, fixed2 n); fixed3 ldexp(fixed3 x, fixed3 n); fixed4 ldexp(fixed4 x, fixed4 n);PARAMETERS
- x
Vector or scalar.
- n
Vector or scalar for power with which to raise 2.
DESCRIPTION
ldexp returns x times 2 raised to the power n.
REFERENCE IMPLEMENTATION
ldexp for float2 vectors x and n could be implemented as:
float2 ldexp(float2 x, float2 n) { return x * exp2(n); }PROFILE SUPPORT
ldexp is supported in all profiles but fp20.
