9.133 IBITS — Bit extraction

Description:

IBITS extracts a field of length LEN from I, starting from bit position POS and extending left for LEN bits. The result is right-justified and the remaining bits are zeroed. The value of POS+LEN must be less than or equal to the value BIT_SIZE(I).

Standard:

Fortran 95 and later

Class:

Elemental function

Syntax:

RESULT = IBITS(I, POS, LEN)

Arguments:

I	The type shall be INTEGER.
POS	The type shall be INTEGER.
LEN	The type shall be INTEGER.

Return value:

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