Floating Point Number Conversion

This package is designed to convert floating point point numbers from their decimal to their binary formats, according to the IEEE 754 standard. This is useful when calculations at the limits of MATLAB precision are performed or when the binary strings are of interest, such as in genetic algorithms. The package consists of the following four scripts.

float2bin: converts decimal floating point numbers to IEEE 754 binary string

bin2float: converts binary string to floating point number

bitstr2vec: converts binary string to binary vector of 0s and 1s

bitvec2str: converts binary vector to binary string

The floating point format that Matlab utilizes and some functions relating to floating point precision and limits are described in this post:
