A library for parsing and evaluating mathematical expressions, supporting real numbers, vectors, and basic interval arithmetic.

2.0.2 - 2021-01-08 #

  • Lower precedence of unary minus below power operator to match common mathematics conventions so that -x^y is parsed as -(x^y) instead of (-x)^y

2.0.1 - 2020-09-07 #

  • Add ability to unbind variable names (by wdavies973)
  • Fix parsing of ceil function (by pepsin)

2.0.0 - 2020-03-08 #

  • Drop support for Dart SDK versions below 2.1.1
  • Enable unnecessary_new lint rule
  • Parser throws FormatException instead of StateError or ArgumentError for invalid input string
  • Remove underscore syntax previously supported for unary minus
  • Fix toString() parser compatibility for the following expressions:
    • Logarithm function: Change string representation from log_b(x) to log(b, x)
    • N-th root function: Change string representation from nrt_n(x) to nrt(n, x)
    • Exponential function: Change string representation from exp(x) to e(x)
