# Fortran Wiki ibits

## 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.
