|

* 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.
