How to generate a random number in 5 decimal points in the range between 0 and 10 with 0.1 intervals? Sample random numbers are like 5.4321, 3.5678, 7.7891 etc.

How are those example numbers on .1 intervals? On a .1 interval I am thinking you want numbers like:
.6, 2.4, 9.1, 5.3
Your two criteria seem to conflict with each other.

You cannot do what you want. Your example random number of 5.4321 cannot be represented exactly as a float.
sprintf('%20.18f\n', 5.4321)
You would be better off generating random integers between 0 and 10^5. I also have no idea what an interval of 0.1 means nor have you said what distribution you want.
