[IMP] tools: float_utils, precision rounding must be positive

Adding a new rule to verify that precision_rounding is positive.

Before this commit:
when a precision_round was 0 or smaller than 0 the float_utils
functions gave as results:
* float_is_zero(0.0, precision_rounding=0.0) -> False
* float_round(1.25, precision_rounding=0.0) -> 0.0
* float_compare(1.0, 1.0, precision_rounding=0.0) -> 1

These results where at least not correct at worst not logic.

Now, the function raises an error when the precision_rounding
is not positive
