Must be this new maths thing I have heard about

I don’t quite get how they worked out the total number of members in the above Facebook group.

Maybe they have floating point multiplication issues. I'm mid way through programming an online ordering system and whenever someone orders 1 item worth £5.02, the total order value is £5.01.

I've done the arithmetic in my head that is used to calculate totals, and I've done it on a calculator, and the equation in the code is right, it's just the computer is incapable of giving the right answer. Most bizzare.

This sounds like what plagued the Pentium IV back in the day. Is it always off by a penny or does it change constantly?
Dad and I saw some abacuses at a restaurant last week and I suggested he work out our total using one. (He used one professionally when he was younger and they are remarkably quick and accurate when one knows the moves.)
