Online Computing System for Octuple-Precision Computation With Fortran
Computations with higher than the IEEE 754 standard double-precision (about 16 significant digits) are required recently. Although, there are available software routines in Fortran and C for high-precision computation, users are required to implement such routines in their own computers with detailed knowledges about them. The authors have constructed an user-friendly online system for octuple-precision computation. In their Web system users with no knowledges about high-precision computation can easily perform octuple-precision computations, by choosing mathematical functions with argument(s) inputted, by writing simple mathematical expression(s) or by uploading C program(s).
