  • Implemented BigNumber implementations of most trigonometric functions: sin, cos, tan, asin, acos, atan, cosh, sinh, tanh. Thanks @BigFav.
  • Implemented function trace. Thanks @pcorey.
  • Faster loading of BigNumber configuration with a high precision by lazy loading constants like pi and e.
  • Fixed constants NaN and Infinity not being BigNumber objects when BigNumbers are configured.
  • Fixed missing parentheses in the toTex representation of function permutations.

Changelog

Source

2014-12-25, version 1.2.0

  • Support for boolean operations and, not, or, xor. Thanks @BigFav.
  • Support for gamma function. Thanks @BigFav.
  • Converting a unit without value will now result in a unit with value, i.e. inch in cm will return 2.54 cm instead of cm.
  • Improved accuracy of sinh and complex cos and sin. Thanks @pavpanchekha.
  • Renamed function select to chain. The old function select will remain functional until math.js v2.0.
  • Upgraded to decimal.js v4.0.1 (BigNumber library).

    • Documented the API.
    • Implemented recursive functions clone, map, forEach, traverse, transform, and filter for expression trees.
    • Parameter index in the callbacks of map and forEach are now cloned for every callback.
    • Some internal refactoring inside nodes to make the API consistent:
      • Renamed params to args and vice versa to make things consistent.
      • Renamed Block.nodes to Block.blocks.
      • FunctionNode now has a name: string instead of a symbol: SymbolNode.
      • Changed constructor of RangeNode to new RangeNode(start: Node, end: Node [, step: Node]).
      • Nodes for a BlockNode must now be passed via the constructor instead of via a function add.
  • Fixed 2e giving a syntax error instead of being parsed as 2 * e.
