Ok. This bug causes any variable that has been used as input argument by Screen->DrawInteger function will be truncated to nearest integer before being drawn onto screen. For instance, PI renders as 3.000 (decimal places arguent is set to maximum), Sin(60) shows as 0 etc. The "decimal places" arguent is rendered useless by this bug.
Screen->DrawInteger truncates input value.
Fixed.
Whoops. Sorry about that. I had simply forgotten about this.
