NAME SHIFTR - Performs a right shift with zero fill SYNOPSIS SHIFTR ([I=]i,[J=]j) IMPLEMENTATION UNICOS, UNICOS/mk, IRIX systems CF90, MIPSpro 7 Fortran 90 STANDARDS Fortran extension DESCRIPTION The SHIFTR intrinsic function performs a right shift with zero fill of the i by j bits. It accepts the following arguments: i The value to be shifted. i can be of type Boolean, integer, real, or Cray pointer. j The number of bits to shift the value. Must be of type integer or Boolean. j must be within the range 0 <= j <=size, where size is the size, in bits, of i. That is, if i is a 64-bit object, j must be within the range 0 <= j <= 64. On UNICOS systems, an object is 64 bits. On UNICOS/mk systems, an object is 32 bits or 64 bits. On IRIX systems, an object is 8 bits, 16 bits, 32 bits, or 64 bits. SHIFTR is an elemental function. The name of this intrinsic cannot be passed as an argument. NOTES This is an outmoded routine. Refer to the Fortran Language Reference Manual, Volume 2, for information about outmoded features and their preferred standard alternatives. The bit representation of the logical data type is not consistent among UNICOS and UNICOS/mk systems. For further details, see your compiler's reference manuals. RETURN VALUES SHIFTR returns a value of type Boolean on UNICOS and UNICOS/mk systems. It returns an integer result on IRIX systems. EXAMPLES The following section of Fortran code shows the SHIFTR function used in the case where i is of type integer. The bit pattern of i and the bit pattern of the result are also given. For simplicity, a 16-bit object is used. INTEGER I1, I2, I3 ...
