NAME
    floatToIntBits - returns the 32-bit integer representation of an IEEE
    754 floating-point scalar or vector

SYNOPSIS
      int  floatToIntBits(float  x);
      int1 floatToIntBits(float1 x);
      int2 floatToIntBits(float2 x);
      int3 floatToIntBits(float3 x);
      int4 floatToIntBits(float4 x);
 
PARAMETERS
    x       Floating-point vector or scalar to 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.

    Not-A-Number (NaN) floating-point values are cannonicalized to the
    integer value 0x7fc00000 regardless of the specific NaN encoding. The
    sign bit of the NaN is discarded.

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

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

    floatToIntBits requires instructions to be generated to cannonicalize
    NaN values so floatToIntBits is typically more expensive than
    floatToRawIntBits.

REFERENCE IMPLEMENTATION
    floatToIntBits operates consistent with the following ANSI C code:

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

        if (isnan(x)) {
          return 0x7fc00000;
        } else {
          u.f = x;
          return u.i;
        }
      }

PROFILE SUPPORT
    floatToIntBits is supported by the the gp4vp manpage, the gp4gp manpage,
    and the gp4vp manpage profiles.

    floatToIntBits is *not* supported by pre-G80 profiles.
