8.117 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.
