Number Formatting Methods

There are predefined methods for number formatting:

Localization

var string1 = webix.i18n.numberFormat("123.45");
var string2 = webix.i18n.intFormat("123.45")
var string3 = webix.i18n.priceFormat("123.45");

They will format data according to rules stated in the current locale.

Applying locales within component:

//datatable
{ header:"LongDate", width:170,  id:"start", format:webix.i18n.numberFormat }
 
//other components
template:function(obj) {return webix.i18n.numberFormat(obj.start); }

Dive into Date and Number localization article.

Custom Formatting

If you need to format number with custom formatting rules you can use methods in the Number class that offers two methods: format and numToStr.

Here you need to specify rules right in a data component.

var string1 = webix.Number.format("123.45",{
    groupDelimiter:",",
    groupSize:3,
    decimalDelimiter:".",
    decimalSize:2
});

Applying format within a component:

//datatable
{ header:"LongDate", width:170,  id:"votes", format:webix.Number.numToStr({
    groupDelimiter:"",
    groupSize:0,
    decimalDelimiter:",",
    decimalSize:5
   }); 
}
 
//other components
template:function(obj) {
    return webix.Number.numToStr(obj.votes, {
        groupDelimiter:"",
        groupSize:0,
        decimalDelimiter:",",
        decimalSize:5   
    });
}
