i was writing a small program, but ran into this error.

Virtual Machine Error
Addr:69
Func:main
Attempt to ^ floats.

could someone explain this error? is this a limitation of PocketC, or is it a basic rule when dealing with C/C++ (or other programming langauges)?

if it is a basic rule when dealing with programming langauges, a pointer to a URL with methods for dealing with this type of math would be greatly appreciated.

thanks.

My C tells me that you can only perform a bitwise exclusive or to integral operands such as char, short, int and long. I am not sure of the C++ equivalent, I just assumed the same was true. There I could be wrong. A link that may or may not help.

Happy Coding,

In C/C++, the ^ operator is bitwise exclusive OR, which makes no sense for a float. In some languages ^ is the 'power' operator (I can't think of the actual term right now), as in 2 ^ 3 = 8. If that is what you intended, you are looking for the pow() function.
