# Pascal - Arithmatic Operators

Advertisements

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
