"Send Max" button results in "Too Many Decimals"

[SZemanek]

I was just experimenting with ZecWallet Lite. I sent a couple cents to a newly created wallet, and went to send it all back, I hit the "send max" and it put in a poorly rounded number and gave me an error of "Too Many Decimals". (see screenshot)

I did this again, and it worked properly the second time I tried it with just a few cents. So this isn't always reproducible. But I'm guessing the way it calculates the "max amount" has some kind of rounding error somewhere.

@adityapk00 I'm finding this issue is still present in v1.8.7. In my case, it results in a calculation beyond the 8-decimal precision. ending in a 1: 0,1234567800000001
