bool(3F)                                                 bool(3F)



NAME
     and, or, xor, not, lshift, rshift - Fortran bitwise  boolean
     functions

SYNOPSIS
     integer i, j, k
     real a, b, c
     double precision dp1, dp2, dp3

     k=and(i, j)
     c=or(a, b)
     j=xor(i, a)
     j=not(i)
     k=lshift(i, j)
     k=rshift(i, j)

DESCRIPTION
     The generic intrinsic boolean functions and, or, and xor
     return the value of the binary operations on their
     arguments.  not is a unary operator returning the one's
     complement of its argument.  lshift and rshift return the
     value of the first argument shifted left or right,
     respectively, the number of times specified by the second
     (integer) argument.

     The boolean functions are generic, that is, defined for all
     data types as arguments and return values.  Where required,
     the compiler generates appropriate type conversions.

LIMITATIONS
     The implementation of the shift functions may cause large
     shift values to deliver unexpected results.

NOTES
     Although defined for all data types, use of boolean
     functions on non-integer data is not productive.
