asuint function

Reinterprets the bit pattern of a 64-bit value as two unsigned 32-bit integers.

Syntax

void asuint(
  in  double value,
  out uint lowbits,
  out uint highbits
);

Parameters

value [in]

Type: double

The input value.

lowbits [out]

Type: uint

The low 32-bit pattern of value.

highbits [out]

Type: uint

The high 32-bit pattern of value.

Return value

This function does not return a value.

Remarks

This function is an alternate version of the asuint intrinsic that has been available in earlier shader models, and was introduced for Shader Model 5. The original function (recognized in the HLSL compiler by its different signature) remains available to Shader Model 5.

Minimum Shader Model

This function is supported in the following shader models.

Shader Model	Supported
Shader Model 5 and higher shader models	yes
