You should be able to remove the ...00005, since epsilon is sufficiently large

Also -0.98999 is strange, expected -.99

I expected 10.5 mod 1.1 to be 0.6, I'm surprised 0.5 is the answer? It also doesn't seem like epsilon is high enough to tolerate this error, I'm surprised this is passing.
Also shocked at how far off -99.5 mod -3 is from .5, should we add -Gis to the compilation options perhaps to improve precision?

Yeah the comment on the value was wrong, it was 1 not 1.1; Added Gis and have set the reuslt to -.5
