SCIEQS 1.1 by George Yee ($6.00) Scientific Equation Solver (SCIEQS) acts as a sophisticated scientific calculator. It can perform double precision floating point arithmetic using an assignment statement syntax similar to BASIC or FORTRAN. Variables may be assigned values in one statement and then used on the right-hand side of another statement. Almost every built-in function found on scientific calculators has been included: trigonometric, hyperbolic, exponential, logarithmic, factorial, and square/cube root functions. Even advanced functions such as erf(x) and gamma(x) have been included. You can also define your own functions with any number of arguments. There is also an equation solver built into the program. This feature allows the program to solve for any variable in a given equation.
