Base 3 to 10

Question

Hi, I’m Lisa, a French programmer and I try for a few days to convert a number from base 3 to 10 without using the int () function. Can anybody help me ?

Answer 1

Understanding number systems and bases seems daunting but the logic behind it is quite simple.

Here's a helpful link.

Example:
1201 base 3 to base 10

1 x 3^0 = 1
0 x 3^1 = 0
2 x 3^2 = 18
1 x 3^3 = 27

1 + 0 + 18 + 27 = 46

1021 base3 == 46 base10
