### modulus(dividend, divisor)
Get the modulus of two numbers, i.e., remainder when the dividend is divided by the divisor. Note that both divisor and dividend need to be integers.
```javascript
var remainder = bigDecimal.modulus('45', '4'); // remainder = '1'
```
Alternately, use the instance property. It returns the result as new `bigDecimal`.
```javascript
var n1 = new bigDecimal('45');
var n2 = new bigDecimal('4');
var remainder = n1.modulus(n2); // remainder = new bigDecimal('1')
```
Further, the result takes the sign of the dividend and the sign of the divisor is ignored. Note that this behaviour is the same as in Java and JavaScript.
