Angular’s built in number filter allows one to specify the number of decimals that should be displayed.
The syntax is as follows:
{{val | number:<count>}}
Where val is the value to be displayed, number is the filtername and count is the number of decimals to be displayed.
For eg.:
If val is 1234.56789
{{val | number:2}}
Displays: 1234.56
{{val | number:0}}
Displays: 1235
{{val | number:4}}
Displays: 1234.5679
