SQRT(3F)                             SysV                             SQRT(3F)



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

SYNOPSIS
     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 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.  sqrt, the
     generic form, will become dsqrt or csqrt as required by its argument
     type.
