Simon McVittie a7bd18c0d5 test: Don't accept results that are much less than expected 
While looking at the other tests in this file, I noticed that instead
of checking for a result in the range of expected ± FLT_EPSILON as I
would have expected, these tests would accept any result strictly less
than expected + FLT_EPSILON, for example a wrong result that is very
large and negative. This is presumably not what was intended, so add
the SDL_fabs() that I assume was meant to be here.
