8.157 LSHIFT — Left shift bits

Description:

LSHIFT returns a value corresponding to I with all of the bits shifted left by SHIFT places. If the absolute value of SHIFT is greater than BIT_SIZE(I), the value is undefined. Bits shifted out from the left end are lost; zeros are shifted in from the opposite end.

This function has been superseded by the ISHFT intrinsic, which is standard in Fortran 95 and later, and the SHIFTL intrinsic, which is standard in Fortran 2008 and later.

Standard:

GNU extension

Class:

Elemental function

Syntax:

RESULT = LSHIFT(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.
