Hello All,
I have an integer variable - lets call it $scaleHeight - somewhere between 0 and 1200. In all
likelihood this variable will not be a multiple of 50. It will be 49 or 51 or 1143 or 856 ...
How do I round $scaleHeight to the Nearest Multiple of 50?
The reason I wish to do this is to obtain a variable which I can then use in a switch statement,
which is clearer to code and faster to run than a whole lot of if statements.
Anyone know the answer?
Regards,
Richard Creech
