How can i round of a variable to some precison

#1

kindly share the code for rounding off a variable in the programme, say i want to round off to 3 digits

#2

you can use setprecision():

#3

I don’t want to print I just want to store a variable in rounded off form
like say float var = 4.234; now I want to round off var

#4

i don’t know any such function
i think it doesn’t exist because nos are stored according to its data type like (int,float,etc)

#5

okay, even I couldn’t even find any such fn.
