Notice. New forum software under development. It's going to miss a few functions and look a bit ugly for a while, but I'm working on it full time now as the old forum was too unstable. Couple days, all good. If you notice any issues, please contact me.

Quote And when I tried to discuss it with my Maths teacher wife she just wanted to have an argument and disown me for using the term "minus" rather than "negative" or "subtract"

And there is the problem. "Minus" can be a catch-all for "negative" or "subtract" but they are not quite the same. "negative" is a property of the number to which it is attached and "subtract" is an operator.

3 - 2 and 3 + -2 give the same result but - 2 and -2 are not the same. the first is two items, an operator and a number the second is just a number.

Basic ignores spaces in expressions making it ambiguous unless () are used to clarify.

Quote Easily sorted. Don't use silly maths. Check your bounds first. :)

Makes me wonder how to implement complex variables. I guess they have certain number of bytes for handling/storage etc, and then the math libraries cogitate on them easily enough. Probably need to define a complex number datatype ..

Not trying it though !!!
