Simple useful Math library written in tiny TypeScript module. | ||
|
||
## API | ||
|
||
### `UnicodeDigits(fromLanguages: Array<UnicodeLangKeys> | 'all' | 'common', toLanguage: UnicodeLangKeys)` | ||
|
||
Translate number. | ||
|
||
- **fromLanguages** The source language to be translated. | ||
- **toLanguages** The dest language to be translated. | ||
|
||
Example: | ||
|
||
```ts | ||
const unicodeDigits = new UnicodeDigits('common', 'en'); | ||
|
||
const list = [ | ||
'0123456789', | ||
'٠١٢٣٤٥٦٧٨٩', | ||
'߀߁߂߃߄߅߆߇߈߉', | ||
'०१२३४५६७८९', | ||
'০১২৩৪৫৬৭৮৯', | ||
'੦੧੨੩੪੫੬੭੮੯', | ||
'૦૧૨૩૪૫૬૭૮૯', | ||
'୦୧୨୩୪୫୬୭୮୯', | ||
'௦௧௨௩௪௫௬௭௮௯', | ||
].join('\n'); | ||
|
||
console.log(unicodeDigits.translate(list)); | ||
``` | ||
|
||
### `unicodeDigits.translate(str: string): string` | ||
|
||
Convert the String of number of the source language to the destination language. | ||
|
||
- **str** is String of number of the source language. | ||
|
||
@TODO: update from ts files docs | ||
|
||
### `isNumber(value: unknown): boolean` | ||
|
||
Check the value is number or can convert to a number, for example string ' 123 ' can be converted to 123. | ||
|
||
#### Why is this needed? | ||
|
||
```ts | ||
console.log(typeof '123'); //=> 'string' | ||
console.log(+[]); //=> 0 | ||
console.log(+''); //=> 0 | ||
console.log(+' '); //=> 0 | ||
console.log(typeof NaN); //=> 'number' | ||
console.log(typeof Infinity); //=> 'number' | ||
``` | ||
|
||
#### True | ||
|
||
<!-- prettier-ignore --> | ||
```ts | ||
import {isNumber} from 'https://esm.run/@alwatr/math'; | ||
|
||
isNumber(5e3); // true | ||
isNumber(0xff); // true | ||
isNumber(-1.1); // true | ||
isNumber(0); // true | ||
isNumber(1); // true | ||
isNumber(1.1); // true | ||
isNumber('-1.1'); // true | ||
isNumber('0'); // true | ||
isNumber('0xff'); // true | ||
isNumber('1'); // true | ||
isNumber('1.1'); // true | ||
isNumber('5e3'); // true | ||
isNumber('012'); // true | ||
isNumber(parseInt('012')); // true | ||
isNumber(parseFloat('012')); // true | ||
``` | ||
|
||
#### False | ||
|
||
<!-- prettier-ignore --> | ||
```ts | ||
import {isNumber} from 'https://esm.run/@alwatr/math'; | ||
|
||
isNumber(Infinity); // false | ||
isNumber(NaN); // false | ||
isNumber(null); // false | ||
isNumber(undefined); // false | ||
isNumber(''); // false | ||
isNumber(' '); // false | ||
isNumber('foo'); // false | ||
isNumber([1]); // false | ||
isNumber([]); // false | ||
isNumber(function () {}); // false | ||
isNumber({}); // false | ||
``` | ||
|
||
### `transformToRange(x: number, options}): number` | ||
|
||
Transform a number from one range to another. | ||
|
||
Options: | ||
|
||
```ts | ||
{ | ||
/** | ||
* The input range [min, max]. | ||
* | ||
*/ | ||
in: [number, number]; | ||
|
||
/** | ||
* The output (request) range [min, max]. | ||
*/ | ||
out: [number, number]; | ||
|
||
/** | ||
* If true, the output will be bounded to the output range (between min and max). | ||
* | ||
* In default behavior when x (input number) does not between input min~max range, | ||
* the output value will be out of output min~max range. | ||
* | ||
*/ | ||
bound?: boolean; | ||
} | ||
``` | ||
|
||
#### Example | ||
|
||
```ts | ||
transformToRange(5, {in: [0, 10], out: [0, 100]}); // => 50 | ||
``` | ||
|
||
Make percentage of any value | ||
|
||
```ts | ||
transformToRange(2000, {in: [0, 5000], out: [0, 100]}); // => 40 | ||
``` | ||
|
||
Calculate progress-bar with | ||
|
||
```ts | ||
const progressOuterWith = 400; //px | ||
const gap = 5; //px (the visual gap between progressBar and component outer). | ||
const currentProgress = 30; //% | ||
|
||
const progressBarWith = transformToRange(currentProgress, { | ||
in: [0, 100], | ||
out: [componentPadding, progressOuterWith - componentPadding], | ||
bound: true, | ||
}); | ||
|
||
this.progressBar.style.width = `${progressBarWith}px`; | ||
``` | ||
|
||
### Generate Random | ||
|
||
### `value` | ||
|
||
Returns a float random number between 0 and 1 (1 Not included). | ||
|
||
```ts | ||
console.log(random.value); // 0.7124123 | ||
``` | ||
|
||
### `random.integer(min: number, max: number): number` | ||
|
||
Generate a random integer between min and max. | ||
|
||
```ts | ||
console.log(random.integer(1, 10)); // somewhere between 1 and 10 | ||
``` | ||
|
||
### `random.float(min: number, max: number): number` | ||
|
||
Generate a random float between min and max. | ||
|
||
```ts | ||
console.log(random.float(1, 10)); // somewhere between 1 and 10 | ||
``` | ||
|
||
### `string: (min: number, max?: number): string` | ||
|
||
Generate a random string with random length. | ||
The string will contain only characters from the characters list. | ||
The length of the string will be between min and max (max included). | ||
If max not specified, the length will be set to min. | ||
|
||
```ts | ||
console.log(random.string(6)); // something like 'Aab1V2' | ||
``` | ||
|
||
### `step(min: number, max: number, step: number): number` | ||
|
||
Generate a random integer between min and max with a step. | ||
|
||
```ts | ||
console.log(random.step(6, 10, 2)); // 6 or 8 or 10 | ||
``` | ||
|
||
### `shuffle(array: any[]): any[]` | ||
|
||
Shuffle an array. | ||
|
||
```ts | ||
const array = [1, 2, 3, 4, 5]; | ||
random.shuffle(array); | ||
console.log(array); // [2, 4, 3, 1, 5] | ||
``` | ||
