In the OCR computing exam should you say float or real?

I don't think it really matters which one you use in the exam. Real numbers, I think, are just another term for floating point numbers (decimals); a float is a single-precision floating point number (so a subset of real numbers).

ok thanks, because i read mark schemes that have both, and mark schemes that don't accept both

Really? I've gone through all the past papers multiple times; I thought it always said equivalent names were allowed, or explicitly said something like "Real/float/single/double" in the mark scheme. Maybe I missed it out or something. Still, though, I'd just say write real numbers rather than floats in the exam, just to be safe.

it's better to know float for OCR because in many questions they've asked what kind of variable is this, or what is the meaning of a float etc.
