print 1,000 instead of 1000?

cainsw

What should I do, if I have a variable which has a numeric value of 1000, and I want to print it as "1,000" instead of "1000"?

By the way, I am new to Twine and to coding. So if anything I said doesn't make sense, please let me know. Thanks!

To do what you want you need to convert your number to a formatted string (text), unfortunately javascript does not have this feature by default so you need to add it.

1. Creating a Script passage and adding the following code to it:


/**
* Number.prototype.format(n, x)
*
* @param integer n: length of decimal
* @param integer x: length of sections
*/
Number.prototype.format = function(n, x) {
var re = '\\d(?=(\\d{' + (x || 3) + '})+' + (n > 0 ? '\\.' : '$') + ')';
return this.toFixed(Math.max(0, ~~n)).replace(new RegExp(re, 'g'), '$&,');
};


2. Test the new format feature by adding the following to your Start passage:


Formating Numbers (no decimal point):
1234 => <<set $a to 1234>><<print $a.format()>>
12345 => <<set $a to 12345>><<print $a.format()>>
123456 => <<set $a to 123456>><<print $a.format()>>
1234567 => <<set $a to 1234567>><<print $a.format()>>
12345678 => <<set $a to 12345689>><<print $a.format()>>


Formating Numbers (with 2 decimal points and roumding):
1234 => <<set $a to 1234>><<print $a.format(2)>>
1234.5 => <<set $a to 1234.5>><<print $a.format(2)>>
1234.56 => <<set $a to 1234.56>><<print $a.format(2)>>
1234.567 => <<set $a to 1234.567>><<print $a.format(2)>>

Formating Numbers (with different decimal points and comma placements):
123456.7 => <<set $a to 123456.7>><<print $a.format(3,2)>>
123456.789 => <<set $a to 123456.789>><<print $a.format(2,4)>>


Hope that helps
