I don't know why printing of float has to go through exact fraction, nor
why 1e-4 is converted to 13743895/137438953472 instead of 1/10000,
however 13743895/137438953472 is technically correct; while printing of
it is wrong. This patch fixed a bug so printing of 1e-4 through
13743895/137438953472 is correct again; which I think is a good
thing. Whether we should improve converting to exact fraction or skip
the convertion altogether is a seperate issue.
