Pascal - Arithmetic Operators
Following table shows all the arithmetic operators supported by Pascal. 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 |
| div |
Divides numerator by denominator |
B div A will give 2 |
| mod |
Modulus Operator AND remainder of after an integer division |
B mod A will give 0 |
The following example illustrates the arithmetic operators −
program calculator;
var
a,b,c : integer;
d: real;
begin
a:=21;
b:=10;
c := a + b;
writeln(' Line 1 - Value of c is ', c );
c := a - b;
writeln('Line 2 - Value of c is ', c );
c := a * b;
writeln('Line 3 - Value of c is ', c );
d := a / b;
writeln('Line 4 - Value of d is ', d:3:2 );
c := a mod b;
writeln('Line 5 - Value of c is ' , c );
c := a div b;
writeln('Line 6 - Value of c is ', c );
end.
Please note that Pascal is very strongly typed programming language, so it would give an error if you try to store the results of a division in an integer type variable. When the above code is compiled and executed, 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 d is 2.10
Line 5 - Value of c is 1
Line 6 - Value of c is 2
