NOTE: NN.print()'s floating point precision, is inucurate at the last decimal digit.

This means that if you copy-paste the printed-weights from the serial output, into another neural-network, there's going to be some slight noise to the output (when you run it). This is a result of Serial.print(weights[i][j], DFLOAT_LEN); where DFLOAT_LEN is 7 but the print-function rounds it in a weirdly way.

I'm looking for solution as of right now

[GiorgosXou]

Usually there will be something like -3.8190280 printed as -3.8190279

Like it's weird ngl.. but it's not something critical :P

[GiorgosXou]

Wait... might not be this, the problem...

Whatever this is, causes the issue:

(Don't worry about the SD read\write [opposite] [str to float] i solved it using ATOL)
