values into p,q sane. Get rid of redundant assignment. Indent
for legibility. NFC.
This doesn't create a functional difference, as all callers
test number >= 0x40000000 anyway.
To see this, note the following:
- consistently, hx is the high bits of x, lx is the low bits,
x is the float.
- & 0x7fffffff zeroes the sign bit, as does fabs.
A case where it isn't easy to see that there's no functional
change is y1, which does:
ix = hx & 0x7fffffff (zero signbit of high bits of x)
y = fabs(x) (this has a zeroed signbit but otherwise same as x)
ix >= 0x40000000
pone(y); qone(y)
qone(x) (also pone) do:
ix = hx & 0x7fffffff
ix in qone and in the calling function are the same number,
and the comparison applies for both, and ix < 0x40000000 isn't
possible.
(Also, no explosions seem to happen when I feed it random numbers)
