      NAME
           sqrt, dsqrt, csqrt - Fortran square root intrinsic function

      SYNTAX
           real r1, r2
           double precision dp1, dp2
           complex cx1, cx2

           r2 = sqrt(r1)

           dp2 = dsqrt(dp1)
           dp2 = sqrt(dp1)

           cx2 = csqrt(cx1)
           cx2 = sqrt(cx1)

      DESCRIPTION
           Sqrt returns the square root of its argument, in the real,
           double-precision, or complex type of its argument.

           Dsqrt returns the double-precision square root of its
           double-precision arguement.

           Csqrt returns the complex square root of its complex
           argument.

           Sqrt works with each type, but the other forms are available
           for programming clarity.
