Alexander Fedosov:
It is strange. I don't remember these functions in mt4 before. Have they been added to fives as well?

ZZY: MQL4 and MQL5 metaquotes are as close as possible to each other (I think the difference is 10-15 functions between the languages), someone from the developers wrote that MQL5 / MQL4 compilers are now completely the same

Alexander Fedosov:
That's odd... I don't remember there being these features in mt4 before. Were they added to fives too?

With the arrival. How's that?

[Alexander Fedosov]

Artyom Trishkin:

Happy arrival. How's it going?

- convert to string and take the extreme digit
- divide by 10, take the remainder - %

Yes, that's it, forgot about the % thank you!
