hi,
Decimal is the system of digital expression where it is basically
assumed that there exists ten numbers. In hexadecimal system, the
basic number are assumed as sixteen. In general practice, there are
two more system too. The binary where the basic number are consider as
two and the octagonal where the basic numbers are consider as eight.
In our daily life, as we understand the numerical system of practice,
the number are in decimal system. In decimal system, the basic number
are 0 1 2 3 4 5 6 7 8 9.
There is no single digit number larger than 9. The larger number than
nine is expressed by two digit figure that is 1 and 0 i.e. 10!
In hexadecimal system, there are sixteen single digit basic numbers.
they are 0 1 2 3 4 5 6 7 8 9 a b c d e f. Here a b c d e f are not
considered as alphabets of English but the numeric expression larger
than nine. I.e. Ten is represented by a, eleven by b, twelve by c and
so on. The larger than fifteen is represented by two digit figure by
the digital symbol 0 to f i.e. sixteen is written as 1 0, seventeen
as 1 1 , eighteen as 1 2 and 255 as ff!!
In octagonal system, there are only eight numbers. They are 0 1 2 3 4
5 6 7. Here larger than seven is expressed by two digit i.e. 1 and 0
i.e. eight is written as 1 0!
Similarly, In binary system, it is considered that there exists only
two basic number! they are 0 and 1. Here, two is written as 1 0, three
as 1 1, and four as 1 0 0!
Mind that The whole computer stand on the binary system!
It means, in binary system 1 0 0 represents as two and in hexadecimal
system. 1 0 0 represents as 256.
Hence In your case, 66 in decimal is sixty Six and it produced the
capital letter B but in hexadecimal system 6 6 means 102 and it
produced the small letter f which its character code. There are
formulas to convert the decimal figure to hexadecimal or octagonal or
binary figures and vice versa.
For further information, please study the fundamentals of computer or
numerical science related literature's.

Hi Umesh, what is the difference between decimal and hexadecimal
representation? Further, what is the precise way to convert the decimal
characters to letters in case there's no NumPad present in a laptop? The
Alt+X command is applicable only for the word programme, what if the code
is
to be converted into a letter in notepad? Even in the word programme
also,
it gives only in hexadecimal while JAWS, by default gives the result in
decimal.

Hi,
66 for capital B is decimal code. 66 for small f is hexodecimal code.
use which one you want. usually, unicode characters are represented in
hexodecimal mode. to get the code for a character spoken by jaws, move
the cursor to it, press numpad 5 thrice quickly. it can give you
decimal or hexodecimal value based on your jaws configuration. to
change it, go to configuration manager, go to graphics and symbols,
check the "speak the character codes in hex" checkbox.
