jMath 1.0.0

jMath is a mathematical library to evaluate complicated expression written as a string. Main features:

• Expressions are stored as Abstract Syntax Tree so the expression can be evaluated many times without re-parsing.
• Expressions can contains variables.
• Support for custom function and operators.
• Functions can be overloaded (resolver chooses function by number of arguments).
• Functions can takes variable number of arguments (variadic functions).
• Expressions can be optimized by optimization passes.
• Support for custom optimization passes.

Library contains set of built-in:

• Constants:
  • numeric: pi, e, inf,
  • logical: true, false,
• Operators:
  • arithmetic: +, -, *, /, ^ (power), - (negation),
  • comparators: =, <>, <, >, <=, >=,
  • logical: not, or, and, xor, nor, nand, <=> (iff), => (consequence),
  • other: % (percentage), mod (modulo),
• Functions:
  • basic: pow, sqrt, root, exp, log, log2, log10, abs, floor, ceil, round, clamp, sgn, indicator,
  • trigonometric: sin, cos, tan, asin, acos, atan, atan2, sinh, cosh, tanh,
  • statistical: min, max, mean, stddev, median,
  • random: rand (uniform), nrand (normal),
  • conversion: to_degrees, to_radians, to_logical,
  • compound: gcd, lcm, factorial, fib, lagrange, poly,
• Optimization passes:
  • BinaryOperatorSimplifying,
  • ConstantFolding,
