Operators for Integers

The following list of operators are specific for integer expressions

Syntax

Remark

Example

expr_intg !

Evaluates factorial of integer expression expr_intg

5! = 5 * 4 * 3 * 2 * 1

| expr_intg |

Absolute value of an integer expression

| -5 | = 5

[ expr_intg1 | expr_intg2 ]

Permutation operator

[ 5 | 3 ] = 60

[ expr_intg1 : expr_intg2 ]

Combination operator

[ 5 : 3 ] = 10

( expr_intg1 | expr_intg2 )

Greatest common divisor

( 27 | 6 ) = 3

( expr_intg1 : expr_intg2 )

Least common multiple

( 27 : 6 ) = 54

Where expr_intg, expr_intg1, and expr_intg2 are any valid integer expressions.
