# ieee754 [](https://travis-ci.org/feross/ieee754) [](https://npmjs.org/package/ieee754) [](https://npmjs.org/package/ieee754)
### Read/write IEEE754 floating point numbers from/to a Buffer or array-like object.
[](https://ci.testling.com/feross/ieee754)
## install
```
npm install ieee754
```
## methods
`var ieee754 = require('ieee754')`
The `ieee754` object has the following functions:
```
ieee754.read = function (buffer, offset, isLE, mLen, nBytes)
ieee754.write = function (buffer, value, offset, isLE, mLen, nBytes)
```
The arguments mean the following:
- buffer = the buffer
- offset = offset into the buffer
- value = value to set (only for `write`)
- isLe = is little endian?
- mLen = mantissa length
- nBytes = number of bytes
## what is ieee754?
The IEEE Standard for Floating-Point Arithmetic (IEEE 754) is a technical standard for floating-point computation. [Read more](http://en.wikipedia.org/wiki/IEEE_floating_point).
