Er, yes? Anything which involves floating point maths?

Your question is to vague to really answer. You are basically saying "I'm 
doing some calculations [what sort of calculations?] with floats [how 
many floats? of what values?], and they're wrong [wrong in what way? how 
badly wrong?] unless there is a valid digit [which digits count as valid 
and which as invalid?] to the left of the decimal point in some number."

Can you extract the float calculations and show us, together with some 
sample data, expected result, and actual result?
