Good morning,

Has anyone noticed and entry lots value being something like .230000000004 in MT5 when you put it as .23 in the code? Is there a way to correct this?

This has been already reported.

The latest release MT5 build has a display problem with showing too many decimal digits. However, internally it is working just as before.

You did not see it before because it was showing less digits.

Is it an appropriate assumption that this will be changed back to its former state?
