College Scientific Calculator 27
A handy, fast, reliable, precise tool if you need to perform complex mathematical calculations Scientific Calculator Precision 27 is programmed in C#. All calculations are done in proprietary data type. The calculator handles mathematical formulas of any length and complexity. Calculation history can be stored into text file or printed. There are ten variables or constants available for storing often used numbers. Precision of calculations is 27 digits. Trigonometric, hyperbolic, inverse and combinatorial functions. Special numbers NaN, Uncertainty, and Infinity. The calculator follows classical approach when uncertainty of f(x) calculation is estimated by formula max|(derivative(f))|*|x*uncertainty(x)|, where maximum of function derivative is considered on interval [x-uncertainty(x),|x+uncertainty(x)], and uncertainty(x)=|x|*10^(-precision). College Scientific Calculator 27 is a shareware categorized under education mathematics tools.

Math Center Level 1
Math software for students studying precalculus. Can be enteresting for teachers teaching precalculus. Math Center Level 1 consists of Graphing calculator 2D, Advanced Calculator, Simple Calculator, Simple Calculator, Simple Rational Calculator, and Simple Integer Calculator called from the Control Panel. Simple calculator is a general purpose calculator which combines use simplicity and calculation power. It handles simple arithmetic operations and complex formulas. Advanced Calculator is a step farther in complexity comparing to the Simple Calculator. The Advanced Calculator has two editing windows. One is for editing x, and the second is for editing f(x). In the x window you can enter any number or formula which contains numbers. In the f(x) window you can enter formulas containing numbers and formulas containing x. First, x will be calculated. Then the result for x will be substituted into the formula for f(x). The presence of two editing windows demands switching between windows. You can do it by clicking buttons "go to x" and "go to f(x)", or by clicking inside the window. If you forget to enter x, then the x=1 will be assumed. If you forget to enter f(x), then f(x)=x will be assumed. Advanced Calculator works in scientific mode. All numbers in internal calculations are treated in scientific format, like 1.23456789012345E+2 for 123.456789012345 Graphing Calculator 2D has two panels. The Left Panel has the Magnifying Square represented by Small Square with gray border on the Left Panel. It is 16 times smaller than the Left Panel. The Right Panel shows content of the Magnifying Square magnified 16 times. You can press button "zoom +". Then the Left and Right Panels will be zoomed twice each. Maximum zoom is 8 (tree clicks of "zoom +"). After that you can click "zoom -". Clicking button "C" (for Center) on Zoom returns picture to starting position with no zoom and Magnifying Square at the center of Left Panel. This is a shareware listed under education mathematics category.

Scientific Calculator Decimal
A handy tool if you need to perform complex mathematical calculations Scientific Calculator Decimal is programmed in C#. All calculations are done in decimal data type. Each calculator has its own advantages. Data type double can operate numbers with large exponent and decimal data type has twice longer mantissa. That is double has about 14-15 digits and decimal has 28-30 digits. Scientific Calculator Decimal will enable you to perform multiple complex operations with ease! The version 1.0.0.1 released on June 30, 2008 has enabled E-button and improved algorithms of trigonometric functions. Now it is possible to calculate trigonometric functions with big arguments. Scientific Calculator Decimal license is shareware and it is listed in education mathematics software.
