9.224 RSHIFT — Right shift bits

Description:

RSHIFT returns a value corresponding to I with all of the bits shifted right by SHIFT places. If the absolute value of SHIFT is greater than BIT_SIZE(I), the value is undefined. Bits shifted out from the right end are lost. The fill is arithmetic: the bits shifted in from the left end are equal to the leftmost bit, which in two’s complement representation is the sign bit.

This function has been superseded by the SHIFTA intrinsic, which is standard in Fortran 2008 and later.

Standard:

GNU extension

Class:

Elemental function

Syntax:

RESULT = RSHIFT(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.
