i came across a bug (im not sure if its a bug or if its supposed to do it) while changing the color of my sprite. i wanted to see what would happen if i did the script that is down below. then it turned my sprite entirely black and white! im not sure if it is supposed to do that or this is a bug.

set [color v] effect to ((1) / (0))

Division by 0 is undefined, so that's probably the case.

((1) / (0))

is infinity

I think it doesn't know what to set the color to, so it just resorts to black.

click on 1/0 it says infinity

i know its kinda cool tho

Before I have to say what I want to say, I have to explain what a floating point number is, just to make sure that we're all on the same page:

In computing, a floating-point number is a type of number that can store a relatively large range of numbers, with a non-fixed number of digits past the decimal point, all in a much smaller space than would normally be required for such versatility - with the caveat that accuracy is limited to a certain number of decimal digits.

JavaScript, the language in which Scratch is written, uses a double-precision floating-point number (also known as a “double float” or just “double”) as its primary type of number (and for a long time, its only type of number). A double float can accurately represent around 15-17 decimal digits - anything more will be rounded to the nearest value that a double float is capable of representing.

With all that said, what I wanted to address:

Although this is correct in a mathematical sense, the IEEE 754 Standard for Floating-Point Arithmetic, the standard on which almost all implementations of floating-point numbers are based on (JavaScript's included), stipulates that dividing a floating-point number by 0 equals Infinity. This is why 1/0 is Infinity, even if it's technically mathematically incorrect.

Something else I wanted to note is that if you write “Infinity” and paste it into the “set color effect to” block (you must capitalize the first letter, otherwise it will be treated as the string “infinity” rather than the number Infinity, in which case nothing will happen), it will also produce the desaturated effect.

im just gonna pretend i understand what you just said

when I receive [what u just said v]
say [mhm got it 0_0] for (2) secs

This happens because 1 divided by 0 is Infinity, therefore Scratch tries to set a number value to letters. Think of it like cloud variables, you can only set them to numbers. However, if you try to set the cloud variable to letters, it fails.

set [☁ score v] to ((1) / (0))

This ^ is the same as this v

set [☁ score v] to [Infinity]

Actually, this isn't quite true. “Infinity” (with a capital I, see my previous post in this topic) actually is a number - and being able to set a cloud variable (which only supports numbers) to Infinity is proof of that.
