# 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`.
