Answer 5

Math percentages and programming operator % aren't related at all...

In computer context, x % y means remainder of the integer division of x by y (named 'modulo' in both math and computer fields).

In math context, x% of y means x hundredths of y, in other words:

value = float(input())
rate = float(input())
percent = value*rate/100
print(str(rate)+'% of',value,'equals',percent)

Answer 6

in js that's the modulo operator ^^

Answer 7

That's already said in my first post...

Answer 8

It's called modular operator.. Gives you reminder of calculation (a%b) in dividend(a) divided by divisor(b).

I included already a example in my first post, see it again..

Division operator is / returns quotiont.
a=30,b=4
document.write(a/b); this prints 7

Modula operator is % returns reminder.
document.write(a%b); this prints 2

A slight difference is calling in programming language.

30% is just 30/100
use that instead when doing calculations then multiply by hundred in the end
