Okay, probably the question is explained not teh best in the theme, so: Say, I have number 90.0777, so how do I floor it until 90.1 using matehmatical function? Yeah, so I guess the question is pure maths, I am just not very good at it, so I hope there is anyone who knows how to help me, cause when I try searching for it in Google it just gives me something I don't need, like the symbol for floor functions or graphs.
