Davout, I think we understand it pretty good, but I will gladly hear what you mean over PM. Also if your feedback is valuable I can assure you it will
come live on the site within hours. I don't want to spam the topic about our new exchange with such information.
Just FYI, we keep the records according to the IEEE 754 decimal32 format - I am sure you are familiar with it if you are asking us about it

IEEE 754 decimal32 is a single-precision floating-point number occupying 32 bits. Tell me I am wrong. Because if I'm not - this is horrible.
Do you know that adding 0.00000001 BTC to 1 BTC will result in 1 BTC, and adding 0.00000021 will result in 1.00000024 BTC with this precision?
