Python round to nearest 0.25 [duplicate]

Answer 1

round is a built-in function in Python 3.4, and print syntax is changed. This works fine in Python 3.4:

def x_round(x):
    print(round(x*4)/4)

x_round(11.20) == 11.25
x_round(11.12) == 11.00
x_round(11.37) == 11.50

Answer 2

The function math.rounddoes not exist, just use the built in round

def x_round(x):
    print(round(x*4)/4)

Note that print is a function in Python 3, so the parentheses are required.

At the moment, your function doesn't return anything. It might be better to return the value from your function, instead of printing it.

def x_round(x):
    return round(x*4)/4

print(x_round(11.20))

If you want to round up, use math.ceil.

def x_round(x):
    return math.ceil(x*4)/4
