Print % sign

#1

I am using the line:

   con.Screen.print("Battery %.2f % full", (Brain.Battery.voltage()/Brain.Battery.capacity())*100);

and I get:
Battery 37.69 full when I want Battery 37.69% full

I tried searching the forum, but could not find anything.
Please Help :slight_smile:
Thanks in advance

Try:

   con.Screen.print("Battery %.2f%% full", (Brain.Battery.voltage()/Brain.Battery.capacity())*100);

% is an escape character, so if you want an actual % in the output you have to put 2 in a row.

Thank you. I will try this out on Tuesday, and tell you how it goes. :slight_smile:

I want to add a bit more onto this. This document is very useful:


Also, if you’re unsure about the “.2” is before f, it’s basically stating how many decimal places to provide after the period.
