Mathematica

Mathematica is a C# library to facilitate mathematical calculations and unit conversions.

Mathematical Expression Evaluation

The library includes ExpressionEvaluator class to facilitate conversion of mathematical expressions provided as string, and returns the calculated result of provided expression.

double result;
result = ExpressionEvaluator.Evaluate("sqrt(9*9)");                   // result = 9
result = ExpressionEvaluator.Evaluate("abs(-5000+1-1) + abs(-5000)"); // result = 10000

Supported operations / operators in order of precedence are:

[], {}, ()
/, *
+, -
sin(x), cos(x), tan(x), sinh(x), cosh(x), tanh(x), asin(x), acos(x), atan(x)
cot(x), sec(x), csc(x), cosec(x)
pow(x, y), loge(x), log10(x), log(N, base), sqrt(x), abs(x)

Unit Conversion

The UnitConverter class included in library facilitates conversion of values from one unit to another.

double result;
result = UnitConverter.ConvertAngle(45, UnitConverter.AngleConversionType.DEGREE_TO_MIL);       // 800
result = UnitConverter.ConvertArea(100, UnitConverter.AreaConversionType.ACRE_TO_SQUARE_METER); // 404687.3

It is a rather simple implementation of its kind, however the unit conversion is done thru generated code.

For details, please see the code of this library as it is intended to be a simplest library in this domain.
