Converting a number to octal ?

GHOSTRIDER2016

Can someone please share with me a simple way of converting a number to octal ? my brain is getting frazzled over these number conversations

Thanks

It's multiplying times 8. The range runs from 0 through 7

0 = 0
1 = 1
7 = 7
10 = 8
11 (8+1) = 9
12 (8+2) = 10
17 (8+7) = 15
20 = 16
30 = 24
40 = 32
100 = 64

Hey there! I remember you asking about decimal (base10) to binary (base2). The same method can be used for decimal (base10) to octal (base. The poster above gave you octal (base to decimal (base 10).

Anyway we are going to use the same number from your binary (500(base10)) to demonstrate conversion to Octal.

As a reminder / is integer division, % is modulus which gives you the remainder (which is the octal digit for that position)

500 / 8 = 62. 500 % 8 = 4 -> 4
62 / 8 = 7. 62 % 8 = 6 -> 6
7 / 8 = 0. 7 % 8 = 7 -> 7

Now we go from the bottom to the top and find that 500(base10) is 764(base.

The process is the same from base10 to any lower base.

I can't edit my post to turn off BB Smilies. (base == ( base8 )
