Arithmetic Operations
All the usual arithmetic operations can be carried out in JavaScript.
Addition:
5 + 4.3;
<< 9.3
Subtraction:
6 - 11;
>> -5
Multiplication:
6 * 7;
<< 42
Division:
3/7;
<<0.42857142857142855
You can also calculate the remainder of a division using the
%
operator:
23%6; // the same as asking 'what is the remainder
↵
when 13 is divided by 6'
<< 5
This is similar to, but not quite the same as, modulo arithmetic. That's because the result
always has the same sign as the first number:
-4%3; // -4 modulo 3 would be 2
<< -1
