@cali.price  You can round a number using {:0.2f} - (where 2 is the number of decimal places):

1
2
3
4
5
integer : float = 5.12692834958

print("integer : {:0.2f}".format(integer))

# Output: integer : 5.13

In Python, you can use the built-in round() function to round a number to a specified number of decimal places.


For example, to round a number to 2 decimal places:

1
2
3
x = 3.14159
rounded_x = round(x, 2)
print(rounded_x) # output: 3.14


You can also use the string formatting method to round a number in python

1
2
3
x = 3.14159
rounded_x = "{:.2f}".format(x)
print(rounded_x) # output: 3.14


You can also use the f-strings method

1
2
3
x = 3.14159
rounded_x = f"{x:.2f}"
print(rounded_x) # output: 3.14


You can specify the number of decimal places to round to by changing the number after the . in the format specifier.
