I'm trying to learn on how to convert a negative decimal number (with fraction) to binary, octal and hexadecimal.
So, base 10: -89.3125
Here is what I did to convert this to binary:
-89= 1011001 (positive) // 0100110 (invert) // +1 (add one) =0100111
I then represent the number in paper as (1)0100111
For the fraction part:
So final result: (1)0100111,1011
Converting this result to Octal: 647,54
And to Hexadecimal: A7,B
I'd like to know if my logic of conversion is correct, for the Octal/Hexadecimal conversion, I simply divided the binary number in groups of 3 and 4 respectively - from right to left before the ',' and left to right after the ','.
I tried finding an online calculator for all of this, but to no success... so I'm kinda shooting in the dark here.
