FRAC bug

I thought I'd work through the HP15C Owners manual as a quick way of testing out each function.

Section 2, page 25 shows the use of INT and FRAC and I found a bug with using FRAC on a negative number.

from the example

123.4567 gINT -> 123.00000 (correct)
g LSTx CHS gINT -> -123.000 (correct)

gLSTx (recalls x: -123.4567) fFRAC -> 0.5433 (incorrect) - should be -0.4567

fFRAC works on positive values of X but is wrong for negative values of X.
