## 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
|
