Tcl - Arithmetic Operators
Following table shows all the arithmetic operators supported by Tcl language. Assume variable ‘A’ holds 10 and variable ‘B’ holds 20, then −
Operator | Description | Example |
---|---|---|
+ | Adds two operands | A + B will give 30 |
- | Subtracts second operand from the first | A - B will give -10 |
* | Multiplies both operands | A * B will give 200 |
/ | Divides numerator by de-numerator | B / A will give 2 |
% | Modulus Operator and remainder of after an integer division | B % A will give 0 |
Example
Try the following example to understand all the arithmetic operators available in Tcl language −
#!/usr/bin/tclsh set a 21 set b 10 set c [expr $a + $b] puts "Line 1 - Value of c is $c\n" set c [expr $a - $b] puts "Line 2 - Value of c is $c\n" set c [expr $a * $b] puts "Line 3 - Value of c is $c\n" set c [expr $a / $b] puts "Line 4 - Value of c is $c\n" set c [expr $a % $b] puts "Line 5 - Value of c is $c\n"
When you compile and execute the above program, it produces the following result −
Line 1 - Value of c is 31 Line 2 - Value of c is 11 Line 3 - Value of c is 210 Line 4 - Value of c is 2 Line 5 - Value of c is 1
