When you mix float and double in the same expression, they have to "equalized" so you are working with the same type of values - much like when you multiply an integer by floating point value, you need to return a float in order to have any accuracy: 13 * 0.6 = 7.8 if you convert the integer to a float, but 13 * 0.6 = 0 if you convert the float to an int!

And a "normal" floating point constant is always a double unless you add the 'F' suffix to make it a float

And the implicit casting that the system does is always "upwards": byte to int, int to float or double, float to double, never the other way around.
So the float values in your array are converted to double values, multiplied by a double constant, and the result is cast - by you - back to a float.

And the problem is that numbers aren't stored in decimal: they are stored in binary (technically in IEEE-754 floating-point standard) and some values just don't "store well": What Every Computer Scientist Should Know About Floating-Point Arithmetic[^]
When you start converting from one floating point size to another, these problems can become exacerbated - which is why the decimal type exists to "reduce the precision" and make things more accurate as a result! Laugh | :laugh:
