It does seem that r.reclass doesn't like floats in it's rules (though it
will reclass floats).  Rules for floats almost always be ranges to cover
the inexact nature of floating point numbers.  I think there may already
be a bug report about this...

Example:

0 thru 2 = 1 Low
2 thru 4 = 2 Medium
4 thru 10 = 3 High
