How can I turn initial value of chaos system to key for encryption algorithm?

I used chaos system for encryption with `(1.00001,3.26,22)` as initial value. I want to use these numbers as key for encryption algorithm.
- Should I turn my number to `(0100001 0326000 2200000)` (normalizing) and turn them to binary? or turn them separately to binary`(1.00001)(3.26)(22)`?
- Is there any function in matlab to convert double to binary like (str2bin)?
Actually i want to Specify how many bits are required for the key?

input of dec2bin must be a non-negative integer. if float to binary conversion is your problem, then write a logic to do the conversion.
However, for chaos generated encryption, logically should support ral x and not just binary x.
that is Xn+1=P*Xn*(1-Xn-1) and all X belong to the Real World.
All of Bifurcation Coefficient, Chaos Input, Chaos Output belong to the Real World if I am right.

Your posted question involves strings, not binary values.
There are multiple competing "standards" on converting double to binary. You need to define the representation you are looking for.

dec2bin(round(S * 10000))
but what do you want to do if the number is negative?
