NAME
ishft(3f) - [FORTRAN:INTRINSIC:BIT MANIPULATION] Shift bits
SYNTAX
result = ishft(i, shift)
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.
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
