ABS(3F-SVR3)        RISC/os Reference Manual         ABS(3F-SVR3)



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.
