Hướng dẫn parsefloat javascript 2 decimal
I have the following code. I would like to have it such that if price_result equals an integer, let's say 10, then I would like to add two decimal places. So 10 would be 10.00. Or if it equals 10.6 would be 10.60. Not sure how to do this.

Internally, it will approximate a decimal fraction according to the rule of floating point arthmetic and handling. It stays a decimal number (floating point, in JS a double) internally, no matter how you many digits you want to display it with. To present it for display, you can choose the precision of the display to whatever you want by string conversion. Presentation is a display issue, not a storage thing. answered Aug 8, 2016 at 10:37
