* double modf(double val, double *iptr)
*
* Returns the fractional part of `val', storing the integer part of
* `val' in *iptr. Both *iptr and the return value have the same sign
* as `val'.
*
* Method:
*
* We use the fpu's normalization hardware to compute the integer portion
* of the double precision argument. Sun IEEE double precision numbers
* have 52 bits of mantissa, 11 bits of exponent, and one bit of sign,
* with the sign occupying bit 31 of word 0, and the exponent bits 30:20
* of word 0. Thus, values >= 2^52 are by definition integers.
*
* If we take a value that is in the range [+0..2^52) and add 2^52, all
* of the fractional bits fall out and all of the integer bits are summed
* with 2^52. If we then subtract 2^52, we get those integer bits back.
* This must be done with rounding set to `towards 0' or `towards -inf'.
* `Toward -inf' fails when the value is 0 (we get -0 back)....
*
* Note that this method will work anywhere, but is machine dependent in
* various aspects.
*
* Stack usage:
* 4@[%fp + SPOFF - 4] saved %fsr
* 4@[%fp + SPOFF - 8] new %fsr with rounding set to `towards 0'
* 8@[%fp + SPOFF - 16] space for moving between %i and %f registers
* Register usage:
* %f0:f1 double val;
* %l0 scratch
* %l1 sign bit (0x80000000)
* %i1 double *iptr;
* %f2:f3 `magic number' 2^52, in fpu registers
