sign(3F)                                                 sign(3F)



NAME
     sign,  isign,  dsign  -  returns  Fortran   transfer-of-sign
     intrinsic functions

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, which devolves to the appropriate
     type depending on its arguments.
