Below is the list of comparison operators:
| Operator | Meaning |
| = | equal, like the == operator below |
| == | equal |
| <> | not equal |
| < | less than |
| <= | less than or equal to |
| > | more than |
| >= | more than or equal to |
Consider the following example of how comparison operations may be used in a program:
00010 ! prompt user and read first number 00020 print "Enter first integer: " 00030 input number1 00040 ! prompt user and read second number 00050 print "Enter second integer: " 00060 input number2 00070 if number1 == number2 then print "number1 is equal to number2" 00080 if number1 <> number2 then print "number1 is not equal to number2" 00090 if number1 < number2 then print "number1 is less than number2" 00100 if number1 > number2 then print "number1 is more than number2" 00110 if number1 <= number2 then print "number1 is less than or equal to number2" 00120 if number1 >= number2 then print "number1 is more than or equal to number2"
