robust-sequence-to-fixed-point

==============================

Converts a non-overlapping increasing sequence of numbers into a fixed point big number representation.

# Example

```javascript

var toFixed = require("robust-to-fixed-point")

var seq = [Math.pow(2, -200), Math.pow(2, 200)]

console.log(toFixed(seq).toString(16))

```

Output:

```javascript

4000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000400000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000

```

# Install

```

npm install robust-sequence-to-fixed-point

```

# API

```javascript

var toFixed = require("robust-sequence-to-fixed-point")

```

#### `toFixed(seq)`

Converts a sequence of floats into a fixed point [bignumber](https://www.npmjs.org/package/bn.js).

* `seq` is a sequence of floating point values

**Returns** A fixed point big integer, with the decimal point at 2^1074.

#### `toFixed.DECIMAL_POINT`

The binary position of the decimal point

Is always `1074`
