How to convert negative number to positive without abs and if

Question

python

Answer 1

Your requirement is strange but I believe basic arithmetic works:-

☑ 0 - negative number = positive number
☑ -1 * negative number = positive number

@Sergey suggestion is same with the latter approach above.

Answer 2

absolute value is the same as
sqrt(x**2)

Answer 3

x=max(-x,x)
it will keep positive, and change the sign of negative, it it works as abs(). :)

Answer 4

You can use number-2*number.

Answer 5

And another, rather silly way, usually applied on variable, -n, where n contains a negative number ;)

Answer 6

thanks for answers all
