sqrt(3F)                                                 sqrt(3F)



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

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

     r2 = sqrt(r1)

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

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

     dx2 = cdsqrt(dx1)
     dx2 = zsqrt(dx1)
     dx2 = sqrt(dx1)

DESCRIPTION
     sqrt returns the real square root of its real argument.
     dsqrt returns the double-precision square root of its
     double-precision argument.  csqrt returns the complex square
     root of its complex argument.  zsqrt and cdsqrt return the
     double-precision complex square root of their double-
     precision complex argument.  sqrt, the generic form, will
     become dsqrt, csqrt or zsqrt as required by its argument
     type.
