ibits(3I)

NAME
     IBITS - Extracts a sequence of bits

SYNOPSIS
     IBITS ([I=]i, [POS=]pos, [LEN=]len)

IMPLEMENTATION
     UNICOS, UNICOS/mk, and IRIX systems

STANDARDS
     Fortran 90

DESCRIPTION
     The IBITS intrinsic function extracts a sequence of bits.  It accepts
     the following arguments:

     i    Must be of type integer.

     pos  Must be of type integer.  It must be nonnegative and pos + len
          must be less than or equal to BIT_SIZE (i).

     len  Must be of type integer and nonnegative.

     IBITS is an elemental function.  The name of this intrinsic cannot be
     passed as an argument.

RETURN VALUES
     The result type and type parameter are the same as i.  The result has
     the value of the sequence of len bits in i beginning at bit pos
     right-adjusted and with all other bits zero.  The bit model defines
     the model for the interpretation of an integer value as a sequence of
     bits.  For more information on the bit model, see the MODELS(3I) man
     page.

EXAMPLES
     IBITS(14, 1, 3) has the value 7.  In this example, the bits are
     numbered from right to left, so they are extracted from right to left.
