The % operator is called the modulus operator (nothing like the mathematical modulus like |-5| = 5).

It will return the remainder of a division, so if you do:

pawn Код:

20 % 10

It will return 0, because 20 goes into 10 twice, with 0 remainder.

However if you do:

pawn Код:

21 % 10

It will return 1, because 21 can be divided into 10 twice (the 20) and then theres 1 remainder.

The ? and : are triadic operators, so the whole function is basically saying:

"If the return value of 'val % 10' is 0, then return true, if there is any remainder, then return false."

So if you plug a value into that function it will return true if the value is divisible by 10, and return false if its not.

You could also use a macro:

pawn Код:

#define IsDivTen(%1) ((%1) % 10)?(false):(true)
