NAME
ibits(3f) - [FORTRAN:INTRINSIC:BIT MANIPULATION] Bit extraction
SYNTAX
result = ibits(i, pos, len)
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).
ARGUMENTS
I The type shall be INTEGER. POS The type shall be INTEGER. A value of zero refers to the least significant bit. LEN The type shall be INTEGER.
RETURN VALUE
The return value is of type INTEGER and of the same kind as I.
STANDARD
[[Fortran 95]] and later
CLASS
[[Elemental procedure|Elemental function]]
