Options

Math.js contains a number of global options. The options are defined in math.options.

precision. The precision used when formatting numbers. A number, default value is 5. The precision is used by the function math.format and by the toString functions of units, complex numbers, and matrices.
matrix.default. The default type of matrix output for functions. Available values are: "array" or "matrix" (default). Where possible, the type of matrix output from functions is determined from the function input: An array as input will return an Array, a Matrix as input will return a Matrix. In case of mixed input or no matrix as input, the type of output is determined by the option math.matrix.default.
