Convert Integer to String Function

I am trying to convert integer to string, but there is no such function. Or at least, I couldn't find one. There is conversion from float to string functions. However, there is no int to string.

Do you know how?

I found a workaround, but I am not sure if this is the right approach.

var int_tst = Convert.stringLength(string_tst);

var float_tst = int_tst + 0.0;

TEXT_2.setText(Convert.floatToString(float_tst,"#0"));

Thanks.
