floatToRawIntBits

> # NAME

> floatToRawIntBits - returns the raw 32-bit integer representation of an IEEE 754 floating-point scalar or vector

> # SYNOPSIS

>       int  floatToRawIntBits(float  x);
>       int1 floatToRawIntBits(float1 x);
>       int2 floatToRawIntBits(float2 x);
>       int3 floatToRawIntBits(float3 x);
>       int4 floatToRawIntBits(float4 x);

> # PARAMETERS

> x

>   Floating-point vector or scalar to raw cast to a scalar int or vector of ints.

> # DESCRIPTION

> Returns a representation of the specified floating-point scalar value or vector values according to the IEEE 754 floating-point "single format" bit layout, preserving Not-a-Number (NaN) values.

> This function is based on Java's jave.lang.Float method of the same name. See:

>       java.sun.com/j2se/1.4.2/docs/api/java/lang/Float.html

> The Cg compiler can typically optimize floatToRawIntBits so it has no instruction cost.

> # REFERENCE IMPLEMENTATION

> floatToRawIntBits operates consistent with the following ANSI C code:

>       int floatToRawIntBits(float  x)
>       {
>         union {
>           float f;  // assuming 32-bit IEEE 754 single-precision
>           int i;    // assuming 32-bit 2's complement int
>         } u;

>         u.f = x;
>         return u.i;
>       }

> # PROFILE SUPPORT

> floatToRawIntBits is supported by the gp4vp, gp4gp, and gp4vp profiles.

> floatToRawIntBits is not supported by pre-G80 profiles.
