How can I convert AC.F3???

I know the AC which would be 172 BUT I am confused about the .F3 The dot gets me confused!!!

What . mean for you in this context?

Where this binary number come from?

Correct is 0ACF3H used in ASSEMBLY programming

Correct is 0xACF3 used in C programming

AC.F3 is invalid type and all compiler get error

pauledwardian, if you are converting from hex to binary, just leave the dot where it is and convert the digits one at a time.

If you are going from binary to hex, then start at the point and group the digits into fours (pad with 0s when needed). Then convert.

Example 101101.01111

Put in groups of 4 from the point 10 1101 . 0111 1

Pad with 0s (if it helps) 0010 1101 . 0111 1000

Convert using the below table (or whatever) 2D.78

0 = 0000

1 = 0001

2 = 0010

3 = 0011

4 = 0100

5 = 0101

6 = 0110

7 = 0111

8 = 1000

9 = 1001

A = 1010

B = 1011

C = 1100

D = 1101

E = 1110

F = 1111

1010 1100 . 1111 0011

in decimal, it would be

172.94921875 <<

ozo,

Can you explain how this conclusion was reached? I've never dealt with base numbers other than 10 that contained decimal points.

Take the number abc.xyz

In decimal

a is hundreds place (10^2)

b is tens place (10^1)

c is ones place (10^0)

x is tenths place (10^-1)

y is hundredths place (10^-2)

z is thousandths place (10^-3)

In binary

a is fours place (2^2)

b is twos place (2^1)

c is ones place (2^0)

x is halves place (2^-1)

y is quarters place (2^-2)

z is eighths place (2^-3)
