attempts to measure how the number of decimals in an operation can affect the speed of the subtraction block (in other words, how much the subtract block is slowed down, as the complexity of the math increases) note: ms stands for milliseconds
-each vertical line represents 10 extra decimal places. -the lower purple line is 0ms, and the higher is 0.0001 ms. It chooses two random (decimal) values, and subtracts them. the algorithm then repeats this subtraction 100,000 times. the total time (in ms) is divided by the number of samples, to find the average time per subtraction. finally, the algorithm will move on to a new amount of decimal places, and continue this process forever some overhead exists, meaning that the raw - operation takes slightly less time
