Hi, my name is Matteo and i am using BigNumber library (version 3.0) in Arduino but i have a problem.
I have seen that if i want to do math operations with numbers with digits after decimal point there is an error.
I try to explain better: if i give to arduino 5.8*2.1 the result is 10 and not 12.18.
Instead if these numbers (5.8 and 2.1) are given from others math operations and then i do 5.8*2.1 the result is right (12.18). Why?
Is there a solution for my problem?
Matteo.

Yes. And when you post your question on the Arduino forum include your code.
