omg...i didnt understand ANYTHING from your explanation to britishgoose01, and i didn't even say the full video(i alreaady knew that)

But how da hell can you convert a "non-full" number(like 23.33) into binary?

As far as i know,you can't...but enlighten me please

[gr1moire2112]

@coladomestre The answer is in the reply to britishgoose01. Using a simpler example of 0.25 decimal. As binary is base 2, multiply .25 by 2 this gives 0.5. Take the 0 of 0.5 this is the first part of the binary equivalent of 0.25. Then take .5 and multiply by 2 this is 1.0 this is a whole number with no decimal so then we take the 1 to give 0.01 being the binary equivalent of decimal 0.25. Does that help ?

ok but if there is an example like 23.33 needs to be converted how do you go about converting it? binary consists of 0's and 1's

[gr1moire2112]

@britishgoose01 Interesting question, for 23 use the method in the videos. 23 = 10111

For the decimal between 0 and 1, in your example 0.33 * 2 = 0.66 note the 0 and then 0.66 * 2 = 1.32 note the 1. So far 01 next 2 * 0.32 = 0.64 note the 0 and 2 * 0.64 = 1.28 so far 01101. Next 0.28 * 2 = 0.56 note the 0 to give 011010 and so on. 0.56 * 2 = 1.02 note the 1 (0110101), 0.2 * 2 = 0.4 note the 0 (01101010) 0.4 * 2 = 0.8 note the 0 (011010100), 0.8 = 1.6 note the 1 (0110101001), etc...

Thats pretty cool I never knew some of this. Im not to good at math though :/
