Fix parsing of decimal input values

[vegeta897]

This fixes 1.5 hours parsing as 5 hours, or 1.0 hours as 0 hours

This was presumably working in 2012 with PR #2 but has since broken.

Now decimal values will parse correctly.

I could add some tests but I'm not sure where I should fit them in among the whole-number tests, or how extensive it should be with all the different test types.

Thanks for this @vegeta897

I did not realise that this was broken 😞

Thats no problem, i'll add a couple of tests and make a new release.

Thanks!
