import type {StringToNumber} from './string-to-number.d.ts';

/**

Returns the absolute value of the specified number or bigint.

@example

```

import type {Absolute} from 'type-fest';

type A = Absolute<-1>;

//=> 1

type B = Absolute<1>;

//=> 1

type C = Absolute<0>;

//=> 0

type D = Absolute<-1.025>;

//=> 1.025

type E = Absolute<-9999n>;

//=> 9999n

```

Returns back the same type if the input is not a literal type.

@example

```

import type {Absolute} from 'type-fest';

type A = Absolute<number>;

//=> number

type B = Absolute<bigint>;

//=> bigint

type C = Absolute<number | bigint>;

//=> number | bigint

```
