SIGN(3F)                COMMAND REFERENCE                SIGN(3F)



NAME
     sign, isign, dsign - FORTRAN transfer-of-sign intrinsic
     function

SYNOPSIS
     integer i, j, k
     real r1, r2, r3
     double precision dp1, dp2, dp3

     k = isign(i, j)
     k = sign(i, j)

     r3 = sign(r1, r2)

     dp3 = dsign(dp1, dp2)
     dp3 = sign(dp1, dp2)

DESCRIPTION
     Isign returns the magnitude of its first argument with the
     sign of its second argument.  Sign and dsign are its real
     and double-precision counterparts, respectively.  The
     generic version is sign and will devolve to the appropriate
     type depending on its arguments.  When using sign, it is
     required that the both arguments be of the same type.
