ScienCalc is a convenient and powerful scientific calculator. ScienCalc calculates mathematical expression. It supports the common arithmetic operations (+, -, *, /) and parentheses. The program contains high-performance arithmetic, trigonometric, hyperbolic and transcendental calculation routines. All the function routines therein map directly to Intel 80387 FPU floating-point machine instructions. Scientific calculator gives students, teachers, scientists and engineers the power to find values for even the most complex equation set. You can build equation set, which can include a wide array of linear and nonlinear models for any application. *Linear equations *Polynomial and rational equations *Nonlinear exponential, logarithmic and power equations *Pre-defined mathematical and physical constants

SimplexCalc is a multivariable desktop calculator for Windows. It is small and simple to use but with much power and versatility underneath. It can be used as an enhanced elementary, scientific, financial or expression calculator. In addition to arithmetic operation, more than hundred built-in constants and functions can also be used in your expression. SimplexCalc also has the unlimited ability to extend itself by using custom (user-defined) variables. You can add your own variables for SimplexCalc in order to tackle complex problems with ease and fun. Even you can compile formula once and then calculate the result many times with different variable values. With the brilliant designs and powerful features of SimplexCalc, you can bring spectacular results to your calculating routines.
