Dan Ellis 6cd2e41918 py/parsenum: Ensure that trailing zeros lead to identical results. ...

Prior to this commit, parsenum would calculate "1e-20" as 1.0*pow(10, -20),
and "1.000e-20" as 1000.0*pow(10, -23); in certain cases, this could make
seemingly-identical values compare as not equal.  This commit watches for
trailing zeros as a special case, and ignores them when appropriate, so
"1.000e-20" is also calculated as 1.0*pow(10, -20).

Fixes issue #5831.
