ABS(3F)                              SysV                              ABS(3F)



NAME
     abs, iabs, dabs, cabs, zabs - FORTRAN absolute value

SYNOPSIS
     integer i1, i2
     real r1, r2
     double precision dp1, dp2
     complex cx1, cx2
     double complex dx1, dx2

     r2 = abs(r1)

     i2 = iabs(i1)
     i2 = abs(i1)

     dp2 = dabs(dp1)
     dp2 = abs(dp1)

     cx2 = cabs(cx1)
     cx2 = abs(cx1)

     dx2 = zabs(dx1)
     dx2 = abs(dx1)

DESCRIPTION
     abs is the family of absolute value functions.  iabs returns the integer
     absolute value of its integer argument.  dabs returns the double-
     precision absolute value of its double-precision argument.  cabs returns
     the complex absolute value of its complex argument.  zabs returns the
     double-complex absolute value of its double-complex argument.  The
     generic form abs returns the type of its argument.
