Hello!

 

can sombody convert and explain how to convert 1.5 to binary

 

Thanks

google "Decimal to binary converter"

 

EDIT-  saw "How"

 

Ummm....... I have no idea, I learned this last year, but I don't play attention.

Binary doesn't have representation for decimal points or fractions. Nevermind there is a way.

I don't think you can convert numbers with decimals to binary, it's either a full number or no number

Maybe this will help?

That doesn't work for values that have numbers behind the decimal point.

 

But binary is mainly used to represent Whole Numbers, it's complicated on fractions.

Here's an explanation of how floating point numbers are represented in binary. Here's a video as well.

I had no idea you could express floating point numbers in binary

Huh.

It is 1.1 = 1 * 2^0 + 1 * 2^(-1)

 

But I'm not in the mood to write a full guide sorry

 

EDIT: This is fixed point arithmetic. Floating point like used in float and double in C for example is quite complicated.

I'll elaborate a bit:

 

64 32 16 8 4 2 1 

.5 .25 .125 .0625

 

Your number is 1.5.

 

There are no 64s, 32s, 16s, 8s, 4s or 2s in that number, but there is one 1.  

 

So this is what you have so far "1."

 

To get the fractional piece you multiply them by two until you get to zero and take the whole numbers as the fractional representation.

 

SO:

 

.5 * 2= 1.0

 

take that one and use it in your answer: 1.1

 

.0 * 2 = 0

 

You're done.
