8.134 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.
Standard:
Fortran 95 and later
Class:
Elemental function
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.
