Free42 with IEEE 754-2008 decimal floating-point -- interested in a sneak preview?

[Paul Dale]

The 31S will have appropriate range reduction code in degrees mode but not in radians (it doesn't support gradians). The code space for this is likely more than we want to commit to on the 34S but I coded the gradians modulo reduction too for future use.

SIN(180°+x) = -SIN(x) fails for x=10^-31, 10^-30, 10^-16 ... and many more (these fail on the WP34 as well btw)
UPDATE (Free42, but not WP34): this is probably due to 1e-31 - 10^-31 not being zero.. in fact 10^x does not produce the correct result for x= integer; even -1..)
SIN(45°) ^= COS(45°)
I can't find the range reduction code straight away, to see what would be wrong with it.. can you point me to it?
