Scratch

Well, I don't suppose it would be very high on the Scratch Teams list of bugs to fix. One ten trillionth is not going to make a difference.

And in addition block, trillionth part _makes_ difference, if you need to be very precise.

Wow, I suddenly realised, the only time it happens is with 1.89, all other numbers work perfectly. I'm gonna do some investigations and see if I can find a way around this.

i've seen this sort of thing before, and it takes many other forms.
There is something wrong with The Way Scratch does Simple Math Functions.
These Weird Numbers are often invisible until you try to use a boolean function on them, and numbers that should be equal, aren't.
This is a problem with even the best scientific programmable calculators, When you are working with numbers that extend to the limits of The Calculator's precision;
But Scratch often changes Small, Nearly Whole Numbers in very odd ways...
Then; The only way to check them is to put all the numbers on a list, and examine the list. When the numbers are displayed on the Variables Blocks in The Display Window, They are usually Rounded Off, and look the way they are supposed too...! But in the Lists, they are apparently recorded in their full precision.

Same thing happen to me! I tried it again and it still works.

I found a glitch in 1.4. I pulled up a "wait ____ secs" block. I wrote 1.89 in the white ovally thing. When I clicked on the script area, the number changed to 1.8900000000000001. Help! I don't want it to wait the extra .00000000000001 of a second!

Thanks aweman. I wrote up a bug report for the development team to take a look at it.  That's pretty weird 

Thanks, Paddle2See.

It's a ten quadrillionth, not a ten trillionth.

For me it gives me 1.6800000000000002, not 1.6800000000000001! This happens with EVERY block! It's weird!

It should be .0000000000000001 of a second.

It can REALLY throw you off for multiplcation (*) or division (/). It is gonna make a difference!

If it's really annoying you why don't you times it by 10000000 (that should be enough decimal places if your calculations go that far, add more if you need to). Then round it and divide by the same number.

There's no 1.4.1 (unless you're on Linux, and it's more like 1.4.01), so it still happens.

Well, you could do 2 wait blocks
