Expression parser of strings like sin(pi/4) is written in c++, javascript, java and php. It is also possible to create functions x0+2*sin(pi*x1) for further calculations.

mXparser is highly flexible parser of math expressions. Software provides easy to use API for JAVA, Android, C# .NET/MONO (CLS). Main functionalities: - basic operators, i.e.: +, -, *, ^, ! - Boolean logic operators i.e.: or, and, xor - binary relations i.e.: =, <, > - math functions (large library of 1-arg, 2-arg, 3-arg - - functions) i.e.: sin, cos, Stirling numbers, log, inverse functions - constants (large library), i.e.: pi, e, golden ratio - n-args functions i.e.: greatest...

1/3 is not 0.33. Pi is not 3.14. Actually 1/3 is in interval [0.33, 0.34] and pi is in interval [3.14, 3.15]. During computation truncating error is accumulating. At end of computation it is needed to know real boundaries of result. The solution is given by interval arithmetic. Simply speaking, because 1/3 is in interval [0.33, 0.34] and 1/7 is in interval [0.14, 0.15], value 1/3 - 1/7 must be in [0.18, 0.2]. Computation can be arbitrary long and complex but interval arithmetic gives...
