Yeah, in Pascal there are three basic kinds of variables. They are integer, real, and character.
Integers are whole numbers, and can not be decimal or fractions (so like 2, 10, -6 would work). Real numbers can be decimals as well as whole numbers (3.25, -9.5, 4.0). The advantage of using integers as opposed to real numbers in Pascal is usually when you use conditional statements and loop statements. Also keep in mind the computer will actually store the number “3″ as something like “3.0000000″ and it may not be exactly equal to three.
The last type of varaiable that I learned in Pascal was character. Basicall, it’s any single letter or symbol (’a', ‘D’, ‘%’).
