How Can I Round a Float to Two Decimal Places in Python?

Rounding to Two Decimals in Python

In Python, decimal rounding can be achieved using the round function. It accepts two arguments: the number to be rounded and the precision or number of decimal places to round to.

To address the issue you encountered in your Fahrenheit to Celsius converter, consider the following code snippet:

def main():
    printC(formeln(typeHere()))

def typeHere():
    global Fahrenheit
    try:
        Fahrenheit = int(input("Hi! Enter Fahrenheit value, and get it in Celsius!\n"))
    except ValueError:
        print("\nYour insertion was not a digit!")
        print("We've put your Fahrenheit value to 50!")
        Fahrenheit = 50
    return Fahrenheit

def formeln(c):
    Celsius = (Fahrenheit - 32.00) * 5.00/9.00
    return Celsius

def printC(answer):
    answer = str(round(answer, 2))  # Round to two decimal places
    print("\nYour Celsius value is " + answer + " C.\n")

main()

Here, in the printC function, we add round(answer, 2) to ensure that the result is rounded to two decimal places. The round function returns a float, so we convert it back to a string (str) before printing.

This modification will now round all Celsius values to two decimal places, giving you a more precise output.
