Computations with higher than the IEEE 754 standard doubleprecision (about 16 significant digits) are required recently. Although there are available software routines in Fortran and C for highprecision computation, users are required to implement such routines in their own computers with detailed knowledges about them. We have constructed an userfriendly online system for octupleprecision computation. In our Web system users with no knowledges about highprecision computation can easily perform octupleprecision computations, by choosing mathematical functions with argument(s) inputted, by writing simple mathematical expression(s) or by uploading C program(s). In this paper we enhance the Web system above by adding the facility of uploading Fortran programs, which have been widely used in scientific computing. To this end we construct converter routines in two stages.
