With this function you can turn any real number into a string. If the real number is an integer, it will be saved with no decimal places, otherwise, it will be saved with two decimal places.
Argument Description string The real number to be turned into a string.
draw_text(100, 100, "Score: " + string(score) + " / Health: " + string(health));
The above code uses the string function to draw both real numbers and strings together (draw will only accept either a string or a real, but not both).
