Abstract

We have examined the differences of computational errors and abilities of UBASIC, N88BASIC and FORTRAN's curve-fitting programs by calculating the least squares method. As a result, the maximum orders of polynomials possible for N88BASIC and MS-FORTRAN was 11th, and for Sun-FORTRAN was 23rd. UBASIC could calculate up to 50th. Calculation of FORTRAN programs made clear to be meaning-less in the higher order of polynomials, because of precisional errors.
