Symbol for irrational number.

A real number that can NOT be made by dividing two integers (an integer has no fractional part). "Irrational" means "no ratio", so it isn't a rational number. We aren't saying it's crazy! Also, its decimal goes on forever without repeating. Example: π (the famous number "pi") is an irrational number, as it can not be made by dividing two integers.
