+### 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).
