### Read/write IEEE754 floating point numbers from/to a Buffer or array-like object.
 | 
						|
 | 
						|
## 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).
