angular 2 pipe decimal places code example
Example 1: angular pipe for 2 decimal places
{{ number | number : '1.2-2'}}
Example 2: angular number pipe
//{{ value_expression | number [ : digitsInfo [ : locale ] ] }}
//Assume someNumber = 12.221
<p>{{ someNumber | number : '1.0-0'}}</p>
//The output here is '12' because we cut the decimals off
//with the number pipe
//More examples from Angular:
//Assume:
//pi: number = 3.14;
//e: number = 2.718281828459045;
<p>e (no formatting): {{e | number}}</p>
<p>e (3.1-5): {{e | number:'3.1-5'}}</p>
<p>e (4.5-5): {{e | number:'4.5-5'}}</p>
<p>e (french): {{e | number:'4.5-5':'fr'}}</p>
<p>pi (no formatting): {{pi | number}}</p>
<p>pi (3.1-5): {{pi | number:'3.1-5'}}</p>
<p>pi (3.5-5): {{pi | number:'3.5-5'}}</p>
<p>-2.5 (1.0-0): {{-2.5 | number:'1.0-0'}}</p>
