How To Get Absolute Value Without 'abs' Function?

def my_abs(value): '''Returns absolute value without using abs function''' if value < 5 : print(value * 1) else: print(value * -1) print(my_abs(3.5)) th

Solution 1:

What does 5 have to do with absolute value?

Following your logic:

defmy_abs(value):
    """Returns absolute value without using abs function"""if value <= 0:
        return value * -1return value * 1print(my_abs(-3.5))
>> 3.5print(my_abs(3.5))
>> 3.5

Other, shorter solutions also exist and can be seen in the other answers.

Solution 2:

The solutions so far don't take into account signed zeros. In all of them, an input of either 0.0 or -0.0 will result in -0.0.

Here is a simple and (as far as I see) correct solution:

defmy_abs(value):
    return (value**2)**(0.5)

Solution 3:

A simple solution for rational numbers would be

def my_abs(value):
    if value<0:
        return -value
    return value

Solution 4:

Why do you want to check if value < 5?

Anyways, to replicate the abs function:

defmy_abs(value):
    return value if value >=0else -1 * value 

Solution 5:

num = float(input("Enter any number: "))
if num < 0 :
    print("Here's the absolute value: ", num*-1)
elif num == 0 :
    print("Here's the absolute value: 0")
elif num > 0 :
    print("Here's the absolute value: ", num)
