I am totally new to nativescript and googling for the some basic stuff is harder than it should be...
What i want to do is basically this: 
I have the number 

1234567.89 

in a variable, and i want to show it in a label with the format

"1,234,567.89"

Also, always show 2 decimals in case that 89 is 0 instead. 

Thanks for the help in advance
