Class

Elemental function

Argument type and attributes

I

An INTENT(IN) INTEGER

SHIFT

An INTENT(IN) INTEGER. Its value must be non-negative, and less than or equal to BIT_SIZE(I).

Result type and attributes

Same as I.

Result value

• The result has the value that is obtained by shifting the bits of I by SHIFT positions to the left, the same as ISHFT(I, SHIFT).
• Vacated bits are filled with zero.
• The bits are numbered 0 to BIT_SIZE(I)-1, from right to left.
