# Fortran Wiki ishft

## Description

ishft returns a value corresponding to i with all of the bits shifted shift places. A value of shift greater than zero corresponds to a left shift, a value of zero corresponds to no shift, and a value less than zero corresponds to a right shift. If the absolute value of shift is greater than bit_size(i), the value is undefined. Bits shifted out from the left end or right end are lost; zeros are shifted in from the opposite end.

## Standard
