# toFloat

Converts a number or numeric string to a `Float`.

```
static Float toFloat();
```

## Parameters

`value`

A numeric or numeric string to convert or validate.

## Return Value

If the value passes validation, this function returns a `Float`; otherwise it throws `ValueNotFloatError`. A value passes validation if it’s a number in the range of a single-precision 32-bit IEEE 754 floating-point value. `toFloat` can also accept a numeric string that represents a number that requires more precision than can be achieved with a JavaScript number.

## Discussion

In TypeScript, `Float` is a branded `BigNumber` type. In JavaScript, it’s a `BigNumber`. `BigNumber` is from the bignumber.js package.

```javascript
import { toFloat } from "@apple/cktool.database";
```
