# toFloat

Converts a number or numeric string to a Float.

## Declaration

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

## Parameters

- `value`: A numeric or numeric string to convert or validate.

## Return Value

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

Discussion In TypeScript, Float is a branded BigNumber type. In JavaScript, it’s a BigNumber. BigNumber is from the bignumber.js package. import { toFloat } from "@apple/cktool.database";
