I need help with the mod and round blocks

enenbee

I know alot about scratch but what is the mod and round block for?

solved

The

block is a new operation called ‘modulo’. You might know the principle from primary school: modulo is a operation to get the remainder of a division. For example 10 mod 3 is 1.

The scratchblock

does exactly was the name says: It rounds the inserted number

Another way to think of

is that it's the “remainder operator”.

Using the example @solved provided,

9 is the closest number that can be divided by 3 perfectly, so the remainder is 1 (or 10 - 9).

The cool thing about ‘mod’ for programming in general is that it forces any input number to be between 0 and one less than the modulo. Got a pile of numbers like 3, 12, 5, 6, 8, 13, 8 and want to pack them into the buckets 0, 1, 2? Then ‘mod 3’ will turn those into 0, 0, 2, 0, 2, 1, 2.

Ok itzg my dad thanks for helping me with the

what can you use the

blocks for in scratch? because i know that the () mod () is where is were if you were to say

the answer would say true instead of false but i don't know what to do with this block like what to use it for

and i don't have any idea what

block does and i also know what the

does so say you have a negative number in there so like

than it would make that number 900 so make the number positive instead of negative just what would you use that for?

and with the

not only do i not know what the abs () of block does but all the options of that block

ok then

why is this glitching now?

Teyla0

ok now its good but the i just don't know what any of those blocks would be used for because like the () mod () block just divides so like the only thing you could use it for would be like a calculator project because you could say like create a new sprite name it calculator and then say
