## 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).
