17 | * Create a user-defined unit and register it with the Unit type.
|
18 | *
|
19 | * Syntax:
|
20 | *
|
21 | * math.createUnit({
|
22 | * baseUnit1: {
|
23 | * aliases: [string, ...]
|
24 | * prefixes: object
|
25 | * },
|
26 | * unit2: {
|
27 | * definition: string,
|
28 | * aliases: [string, ...]
|
29 | * prefixes: object,
|
30 | * offset: number
|
31 | * },
|
32 | * unit3: string // Shortcut
|
33 | * })
|
34 | *
|
35 | * // Another shortcut:
|
36 | * math.createUnit(string, unit : string, [object])
|
37 | *
|
38 | * Examples:
|
39 | *
|
40 | * math.createUnit('foo')
|
41 | * math.createUnit('knot', {definition: '0.514444444 m/s', aliases: ['knots', 'kt', 'kts']})
|
42 | * math.createUnit('mph', '1 mile/hour')
|
43 | *
|
44 | * @param {string} name The name of the new unit. Must be unique. Example: 'knot'
|
45 | * @param {string, Unit} definition Definition of the unit in terms of existing units. For example, '0.514444444 m / s'.
|
46 | * @param {Object} options (optional) An object containing any of the following properties:
|
47 | * - `prefixes {string}` "none", "short", "long", "binary_short", or "binary_long". The default is "none".
|
48 | * - `aliases {Array}` Array of strings. Example: ['knots', 'kt', 'kts']
|
49 | * - `offset {Numeric}` An offset to apply when converting from the unit. For example, the offset for celsius is 273.15. Default is 0.
|
50 | *
|
51 | * See also:
|

|
53 | * unit
|
54 | *
|
55 | * @return {Unit} The new unit
