html - in rails erb file i want to display an output as a decimal only at one place where actually it is showing as a float value - 


<div class='summary' align="justify" style='vertical-align: top;'>   <div>     {{:stats.tot_fte}} employees assigned      &emsp; {{:stats.tot_fte_effort}} total effort   </div>   <div>     {{:stats.tot_users}} users assigned      &emsp;&emsp;&emsp; {{:stats.tot_user_effort}} total effort   </div>  </div>

this code wrote display total effort output calculate total effort @ other place,where should float value use other calculations.but while displaying here want decimal value 2 numbers after decimal.please me in completing beginner. output follows,

340 employees assigned   340.89666666666665 total effort

453 users assigned     452.6066666666666 total effort

i want total effort display decimal value here.

since using rails, comes numbers helper in actionview. can use number_with_precision(number, options = {}).

for example:

number_with_precision 123.456, precision: 2
