UI: fix a precision issue with float field step size.
Fix a precision issue when stepping down from 1 to 0 via the left
decrement button and step 100 results in a small nonzero value.
The reason is that 0.01 can't be precisely represented in binary
and converting to double before multiplication reveals this.
