Decimal 247,37 to hexadecimal I can only do
from 247 to hexa like this:

2*16^2 + 4*16^1 + 7*16^0 = 41.

But .37 how to make that ?


Also i wonder how to make decimal 0.37
to binary code.

Thanks for help

 

Use a negative exponent to make a decimal.

 

To convert decimal to hexadecimal
you have to divide by 16(so for 247 its f7) .
To convert the decimal part multiply the decimal part by 16 and discard the decimal part.

example:0.37 x 16 = 5.92 -> 5

.92 x 16 = 14.72 -> e (for 14)
so 5e.( continuing in a similar way you can get the answer for as many points as you want.)

 

F7.5EB gives F7.5F because B > 8
Answer: F7.5F

Why does teacher said F7.5F and not F7.5EB ?
Please explain because i dont understand the decimal so well.

 

There is some good material on Hex to Dec conversion in the AAC ebook at this link.
