Changelog

Source

2015-02-28, version 1.4.0

  • Implemented trigonometric functions: acosh, acoth, acsch, asech, asinh, atanh, acot, acsc, asec. Thanks @BigFav.

Changelog

Source

2015-02-09, version 1.3.0

  • 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.

1.2.0

 published 1.2.0 •

Changelog

Source

2014-12-25, version 1.2.0

  • Support for bitwise operations bitAnd, bitNot, bitOr, bitXor, leftShift, rightArithShift, and rightLogShift. Thanks @BigFav.
  • 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).

Changelog

Source

2014-11-22, version 1.1.1

  • Fixed Unit divided by Number returning zero.
  • Fixed BigNumber downgrading to Number for a negative base in pow.
  • Fixed some typos in error messaging (thanks @andy0130tw) and docs.

1.1.0

 published 1.1.0 •

Changelog

Source

2014-11-15, version 1.1.0

  • Implemented functions dot (dot product), cross (cross product), and nthRoot.
  • Officially opened up the API of expression trees:
    • 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.

1.0.1

Diff
josdejong
 published 1.0.1 •

Changelog

Source

2014-09-12, version 1.0.1

  • Disabled array notation for ranges in a matrix index in the expression parser (it is confusing and redundant there).
  • Fixed a regression in the build of function subset not being able to return a scalar.
  • Fixed some missing docs and broken links in the docs.

1.0.0

Diff
josdejong
 published 1.0.0 •

Changelog

Source

2014-09-04, version 1.0.0

  • Implemented a function filter(x, test).
  • Removed math.distribution for now, needs some rethinking.
  • math.number can convert units to numbers (requires a second argument)
  • Fixed some precedence issues with the range and conversion operators.
  • Fixed an zero-based issue when getting a matrix subset using an index containing a matrix.

0.27.0

Diff
josdejong
 published 0.27.0 •

Changelog

Source

2014-08-21, version 0.27.0

  • Implemented functions sort(x [, compare]) and flatten(x).
  • Implemented support for null in all functions.
  • Implemented support for "rawArgs" functions in the expression parser. Raw functions are invoked with unevaluated parameters (nodes).
  • Expressions in the expression parser can now be spread over multiple lines, like '2 +\n3'.
  • Changed default value of the option wrap of function math.import to false.
  • Changed the default value for new entries in a resized matrix when to zero. To leave new entries uninitialized, use the new constant math.uninitialized as default value.
  • Renamed transform property from __transform__ to transform, and documented the transform feature.
  • Fixed a bug in math.import not applying options when passing a module name.
  • A returned matrix subset is now only squeezed when the index consists of scalar values, and no longer for ranges resolving into a single value.

0.26.0

Diff
josdejong
 published 0.26.0 •

Changelog

Source

2014-08-03, version 0.26.0

  • A new instance of math.js can no longer be created like math([options]), to prevent side effects from math being a function instead of an object. Instead, use the function math.create([options]) to create a new instance.
  • Implemented BigNumber support for all constants: pi, tau, e, phi, E, LN2, LN10, LOG2E, LOG10E, PI, SQRT1_2, and SQRT2.
  • Implemented BigNumber support for functions gcd, xgcd, and lcm.
  • Fixed function gxcd returning an Array when math.js was configured as {matrix: 'matrix'}.
  • Multi-line expressions now return a ResultSet instead of an Array.
  • Implemented transforms (used right now to transform one-based indices to zero-based for expressions).
  • When used inside the expression parser, functions concat, min, max, and mean expect an one-based dimension number.
  • Functions map and forEach invoke the callback with one-based indices when used from within the expression parser.
  • When adding or removing dimensions when resizing a matrix, the dimensions are added/removed from the inner side (right) instead of outer side (left).
  • Improved index out of range errors.
  • Fixed function concat not accepting a BigNumber for parameter dim.
  • Function squeeze now squeezes both inner and outer singleton dimensions.
  • Output of getting a matrix subset is not automatically squeezed anymore except for scalar output.
  • Renamed FunctionNode to FunctionAssignmentNode, and renamed ParamsNode to FunctionNode for more clarity.
  • Fixed broken auto completion in CLI.
  • Some minor fixes.
