char str[128];

float x;

sprintf(str, "%d", dbObjectPositionX(1));
dbText(1,1 str);

or

dbText(1,1 dbStr(x));
^Causes memory leaks but good for small programs

Ok, I found something else with this, I am using this code to display it:
dbText(0,0,dbStr(x));
dbText(0,10,dbStr(y));
dbText(0,20,dbStr(z));
but my variable is a float (which I need it to be) but I don't want it to DISPLAY the decimal places, or maybe just to 1 or 2 places.

You could cast it to int and then display it. So your code would look like



But I would avoid using dbStr, and just go with using sprintf_s

With the sprintf command you can specify in the format string how many decimal digits you want to display. E.g. %.2f will display two digits after the decimal point.
