There are two math functions,
math.ceil(x) and
math.floor(x).
math.ceil() finds the next integer larger than
x and
math.floor(x) find the next integer smaller than
x.
Write some code that reads a number from the keyboard, using a line like
x=input(). Then, using the
math.ceil() and
math.floor() functions, properly round the number (in
x) to the nearest integer. So 4.5 should round to 5 and 4.3 should round to 4, etc. Your code should display the rounded number to the screen using
print.
You might have to experiment with
math.ceil(x) and
math.floor(x) a bit first. Try, for example
print(math.ceil(5.3)) or
print(math.floor(5.3)). In your math book, these will be called the "greatest" and "least" integer functions.
