Converting HwFP to fraction gives truncated result

[c3d]

Running the following gives a totall wrong result:

HFP 12 PREC
10.3033 FromHMS ToHMS

We expect 10.30.33, instead we get 10:00:00

Initial report

[c3d]

Caused by an incorrect use of - operator on uint value, which causes the epsilon to be very large instead of very small.
