float-bits

==========

Pulls out an integer representation of the bits of a 32-bit float in javascript.  In C/C++, you would do most of this stuff using pointers, for example:

```C++

int float2int(float y) {

  return *(int*)&y;

}

```

## Install

    npm install float-bits

    

## Example

```javascript

> var fb = require("float-bits")

> fb(1.0)

1065353216

> fb.toInt(-1.0)

-1082130432

> fb.fromInt(-1054867456)

-10.0

> fb.toUint(31)

1106771968

> fb.fromUint(1056964608)

0.5

```

### `require("float-bits")(y)`

Returns a signed integer representing the bits of the float encoded by `y`.

### `require("float-bits").toInt(y)`

Same as `require("float-bits")`

### `require("float-bits").fromInt(y)`

Converts a signed integer reprsenting the bits of `y`

### `require("float-bits").toUint(y)`

Converts a float to an unsigned integer

### `require("float-bits").fromUint(y)`

Converts an unsigned integer to a float
