I set a variable as "single" and gather the value from in cell in Excel, say a percentage. When I spit out the same variable back to the worksheet, I got a slightly different number. For example 12% will become 0.1200000000542. Obviously this causes problem when I do data vailadion since these two numbers are now not equal. I don't want to round a number everytime when I deal with a number, any suggestion?

Hi
you have to use Round or something similar. See
http://www.cpearson.com/excel/rounding.htm
for an explanantion why this happens

In addition I won't use 'Single' but 'Double' as variable type. No real
need for a 'Single' variable type
