| 17 | ### Read/write IEEE754 floating point numbers from/to a Buffer or array-like object.
|
| 18 |
|
| 19 | ## install
|
| 20 |
|
| 21 | ```
|
| 22 | npm install ieee754
|
| 23 | ```
|
| 24 |
|
| 25 | ## methods
|
| 26 |
|
| 27 | `var ieee754 = require('ieee754')`
|
| 28 |
|
| 29 | The `ieee754` object has the following functions:
|
| 30 |
|
| 31 | ```
|
| 32 | ieee754.read = function (buffer, offset, isLE, mLen, nBytes)
|
| 33 | ieee754.write = function (buffer, value, offset, isLE, mLen, nBytes)
|
| 34 | ```
|
| 35 |
|
| 36 | The arguments mean the following:
|
| 37 |
|
| 38 | - buffer = the buffer
|
| 39 | - offset = offset into the buffer
|
| 40 | - value = value to set (only for `write`)
|
| 41 | - isLe = is little endian?
|
| 42 | - mLen = mantissa length
|
| 43 | - nBytes = number of bytes
|
| 44 |
|
| 45 | ## what is ieee754?
|
| 46 |
|
| 47 | 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).
