删除胡子内的值中的小数

I'm trying to create a template where one of a text box's value is:

value="{{selection_qty}}";

the value of {{selection_qty}} is decimal

I want to remove the decimal.How could I do it using php?

I tried to put it inside php code but it didn't work.

value="<?php echo number_format({{selection_qty}}); ?>"
