Well now will be different after angular 5:
{{ number | currency :'GBP':'symbol':'1.2-2' }}
Simple solution
{{ orderTotal | number : '1.2-2'}}
//output like this
// public orderTotal = 220.45892221
// {{ orderTotal | number : '1.2-2'}}
// final Output
// 220.45
It's Works
.ts -> pi = 3.1415
.html -> {{ pi | number : '1.0-2' }}
Ouput -> 3.14
