# bitshift

Purpose
Shift an integer by a number of bits.
Synopsis
`function bitshift(i:integer, n:integer):integer`
Arguments

i | Integer to be shifted
n | Number of bits: >0 for shifting to the left and <0 for shifting to the right

Return value
Shifted integer.
Example
In the following, i takes the value 160, j takes the value 32, and k takes the value 1:

    i:= bitshift(5, 5)
    j:= bitshit(1, 5)
    k:= bitshit(128, -7)

Shifting of 1 bit to the right is the same as dividing it by 2 and shifting of 1 bit to the left is the same as multiplying by 2.
