Does anyone know whats wrong with this mt4 code?

[Randon Deemer]

Print("BuyOrdersArray good[1] " +BuyOrdersArray[1]);//digits are 5 like it is supposed to be

Print("BuyOrdersArray good[1] " +BuyOrdersArray[variable here]);//now it goes to 4 digits when you add a variable instead of an integer you can make the code the same but as soon as you put the variable in for the array location it messes up

[Carl Schreiber]

Use DoubleToString()

[William Roeder]

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

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