9.245 SHIFTA — Right shift with fill

Description:

SHIFTA returns a value corresponding to I with all of the bits shifted right by SHIFT places. SHIFT that be nonnegative and less than or equal to BIT_SIZE(I), otherwise the result 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.

Standard:

Fortran 2008 and later

Class:

Elemental function

Syntax:

RESULT = SHIFTA(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.
