LSHIFT (The GNU Fortran Compiler) (original) (raw)

8.181 LSHIFT — Left shift bits ¶

Synopsis:

RESULT = LSHIFT(I, SHIFT)

Description:

LSHIFT returns a value corresponding to I with all of the bits shifted left by SHIFT places. SHIFT shall be nonnegative and less than or equal to BIT_SIZE(I), otherwise the result 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This function has been superseded by the ISHFT intrinsic, which is standard in Fortran 95 and later, and the SHIFTL intrinsic, which is standard in Fortran 2008 and later.

Class:

Elemental function

Arguments:

Return value:

The return value is of type INTEGER and of the same kind asI.

Standard:

GNU extension
