Hello all,
Would someone please tell me if my GrayCode to Binary routine is proper.
The test Ive done so far seem to be accurate but I need further opinion.
with trace
trace(1)
function Gray2Bin(atom Num)
atom junk
junk =3D floor(Num/2)
return xor_bits(Num, junk)
end function
atom a,b,c,d,e,f,g
a=3DGray2Bin(10)
b=3DGray2Bin(11)
c=3DGray2Bin(12)
d=3DGray2Bin(13)
e=3DGray2Bin(14)
f=3DGray2Bin(15)
g=3DGray2Bin(16)
For those who might not know why Gray Code are used, here is a brief explan=
ation:
A Gray Code is a special type of binary code that doesnt use position weigh=
ting, in other
words, each position does not have a specific weight. Gray Code are setup s=
o that as we
progress from one number to the next, only one bit changes. Because only on=
e bit changes
at a time, the speed of transition for Gray Code is considerably faster tha=
n BCD.

Euman
