atan2(3F)                                               atan2(3F)



NAME
     atan2, datan2 - Fortran arctangent intrinsic function

SYNOPSIS
     real r1, r2, r3
     double precision dp1, dp2, dp3

     r3=atan2(r1, r2)

     dp3=datan2(dp1, dp2)
     dp3=atan2(dp1, dp2)

DESCRIPTION
     atan2 returns the arctangent of arg1/arg2 as a real value.
     datan2 returns the double-precision arctangent of its
     double-precision arguments.  The generic form atan2 may be
     used with impunity with double-precision arguments.
