py/formatfloat: Fix rounding of %f format with edge-case FP values.

Browse Source 
Prior to this patch the %f formatting of some FP values could be off by up
to 1, eg '%.0f' % 123 would return "122" (unix x64).  Depending on the FP
precision (single vs double) certain numbers would format correctly, but
others wolud not.  This patch should fix all cases of rounding for %f.
