In this code, what does “x%2 != 0” mean?

I know what != means, more specifically, I don’t know what % means. Is it different than " a fraction of 100"?

This compares the reminder of `x` when divided by two to zero. It effectively determines if `x` is odd.

``````package main

import (
"fmt"
)

func main() {
for x := 0; x < 10; x++ {
isOdd := x%2 != 0
fmt.Printf("%d is isOdd: %t\n", x, isOdd)
}
}
``````

Output:

``````0 is isOdd: false
1 is isOdd: true
2 is isOdd: false
3 is isOdd: true
4 is isOdd: false
5 is isOdd: true
6 is isOdd: false
7 is isOdd: true
8 is isOdd: false
9 is isOdd: true
``````
