JavaScript code to include Maximum and minimum limit for a number Z -

function add(id,value) { var x  = document. element id(id). value ; x = x.replace('$',''); x  = x.replace(',',''); var y = value; var z = +x + +y;     document.get element id(id). value =z; }

to set minimum value z 0 , maximium value 999999999

if question how make sure z never less 0 or greater 999999999, there 2 common ways:

using if:

if (z < 0) {     z = 0; } else if (z > 999999999) {     z = 999999999; }

using math:
```
z = math.max(0, math.min(z, 999999999)); 
```
math.min(z, 999999999) pick smallest of values give it, , won't return value greater 999999999. similarly, math.max(0, ...) return largest of 2 values give it, , won't return value less 0.
