Angular/Typescript numeral.js

Question

I want to format a number to also display the Romanian format for decimals and thousands like this: 1.000,23 . I am using the numeral.js library.

Here is my pipe code:

constructor(private session: SessionService) {
    numeral.register('locale', 'ro', {
        delimiters: {
            thousands: this.session.Settings.groupSymbols,
            decimal: this.session.Settings.decimalSymbols
        },
        abbreviations: {
            thousand: 'k',
            million: 'm',
            billion: 'b',
            trillion: 't'
        },
        ordinal: function (number) {
            return number === 1 ? 'er' : 'ème';
        },
        currency: {
            symbol: 'RON'
        }
    });
    numeral.locale("ro");
}

public transform(value: string) {
    var b = numeral(value);
    var x = "0,0.";
        for (var i = 0; i < this.session.Settings.decimalDigits; i++) {
        x = x + "0";
    }

    return b.format(x);
}

This is the tags output displayed:

<label>{{ '12345678' | decimalUnitPipe }}</label>
<br>
<label>{{ '1.234,5678' | decimalUnitPipe }}</label>
<br>
<label>{{ '1,234.5678' | decimalUnitPipe }}</label>
<br>
<label>{{ '1,2345678' | decimalUnitPipe }}</label>
<br>
<label>{{ '1.2345678' | decimalUnitPipe }}</label>

And this is the output displayed by the browser:

12,345,678.00 
1.23 
1,234.57 
12,345,678.00 
1.23

How can I convert my local to display my numbers in the wanted format like in the label? On the first number, it also displays the decimals (.00) and I do not want them to be displayed if I do not put any decimals in there. In the second one, it shows 1.23 and I want it to show 1.234,5678 etc.

Please help, thanks in advance!
