I used some code from mql5 and it's showing up with long decimals.

It's showing:

Buy 0.230000000000001 Sell 1.750000000000001

Is there a way to shorten the amount of decimals showing up?

martymcfry666 it's showing up with long decimals.

Floating-point has an infinite number of decimals, it's you, not understanding floating-point and that some numbers can't be represented exactly. (like 1/10.)
          Double-precision floating-point format - Wikipedia

See also The == operand. - MQL4 programming forum (2013)

If you want to see the correct number of digits, convert it to a string with the correct/wanted accuracy.
