Horner Value Finder

This Pascal program finds the value of a Nth order polynomial:
a_{n}x^{n}+a_{n-1}x^{n-1}+cdots+a_{1}x+a_{0}
implementing Horner method without using any complex arithmetic in Fortran 77.

Obviously, it can find complex values, for complex x’s, but without complex arithmetic.
The program also uses ANSI codes to clear screen.

Root-o-matic

This little Fortran program, originally written in DOS, uses the arithmetic sequence x_n+1={1/2} x_{n} + A / x_{n} to find the root of A.

All you have to do is to enter A and a guess value x_0

Caution: This program is very old; it uses Escape codes to clear the screen. In DOS, it needs the ANSI.COM driver. I haven’t test it on Linux 😉
