ISHFT — Shift bits

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.

Syntax

RESULT = ISHFT(I, SHIFT)

Arguments

I The type shall be INTEGER.
SHIFT The type shall be INTEGER.

Return value

The return value is of type INTEGER and of the same kind as I.

Standard

Fortran 95 and later
