How hex numbers pronounced (දහසයේ පාදයේ සංඛ්‍යා උච්ඡාරණය)

When working in such fields as mathematics, computing, electronics, we often find the use of hexadecimal (hex) numbers like 6A, 80D, FF. I assume those who are reading this post are knowledgeable with hex numbers; or at least are aware of it. So, I am not going to dwell on its nitty-gritty here.

Anyway, since I was exposed to hex numbers in school, and then was working with them whilst learning computing, and elctronics, I had not known how to sound or rather pronounce a hex number as we do for normal decimal numbers (eg: decimal number "58" is pronounced as "fifty eight"). We just used to pronounce them ditit by digit (eg: "45A" as "four five ai"). It's obvious sounding a number by its individual digits is very much cumbersome and very hard to remember even.

However, I find that even hex numbers could be pronounced in the same style without any difficulty. There are 3 parts you must keep in mind (this is just my idea, and really don't know whether anyone has suggested this or any other method instead before).

1. Any single-digit hex number can be pronounced like:

0 - zero
1 - one
2 - two
3 - three
4 - four
5 - five
6 - six
7 - seven
8 - eight
9 - nine
A - ai
B - bee
C - see
D - dee
E - ee
F - ef

2. Any number between hex 10 to 1F can be pronounced as follows.

10 - ten
11 - eleven
12 - twelve
13 - thirteen
14 - fourteen
15 - fifteen
16 - sixteen
17 - seventeen
18 - eighteen
19 - nineteen

1A - hexteen (aiteen is discarded to prevent it being misunderstood as eighteen)
1B - beeteen
1C - seeteen
1D - deeteen
1E - eeteen
1F - efteen 

3. Just as every normal decimal digit has a prefix form for numbers in the range 20 and 100, each hex digit also should be given its own prefix form as shown below.

2X - twenty X
3X - thirty X
4X - forty X
5X - fifty X
6X - sixty X
7X - seventy X
8X - eighty X
9X - ninety X
AX - hexty X
BX - beety X
CX - seety X
DX - deety X
EX - eety X
FX - efty X

Using the above rules, now you can easily pronounce any hex number. Following are some examples.

1 - one
B - bee
19 - nineteen
1C - seeteen
25 - twenty five
2A - twenty ai (twenty A)
3B - thirty bee (thirty B)

9C - ninety see (ninety C)
D8 - deety eight
AF - hexty ef
100 - one hundred
130 - one hundred and thirty
15D - one hundred and fifty dee (one hundred and fifty D)
B2E - bee hundred and twenty ee
275E - two thousand seven hundred and fifty ee (two thousand seven hundred and fifty E)
7A62F - seventy ai thousand six hundred and twenty ef (seventy four thousand six hundred and twenty f)
C00,000 - see hundred thousand
B,000,000 - bee million
F,000,000,000 - ef billion
D,000,000,000,000 - dee trillion
A,000,000,000,000,000 - ai quadrillion
C,000,000,000,000,000,000 - see quintillion
E,000,000,000,000,000,000,000 - ee hexillion
etc...

  1. after writing this post, I searched on the Internet on this matter. It seems several models have been suggested, but none is standard. However, I found someone has proposed a model (https://stackoverflow.com/questions/4701470/how-do-you-pronounce-large-hex-numbers) which is almost the same as my method, so I am definitely not the first, but I call myself an original creator (anyway, my method is slightly different and slightly easier than the above one even).

    මම row data මඟින් bitmap image හදන්න මෘදුකාංගයක් හැදුවා.
    ඒ වගේම mp3, mp4 ෆයිල් වල ගායකයාගේ නම වගේ දත්ත ලබා ගන්නත් දන්නවා.

    1. ඔබ සඳහන් කරන්නේ ෆයිල්වල metadata ගැනනෙ... මා මේ ගැන බොහෝ කලකට පෙර (ඉගෙන ගන්න කාලයේ) සොයා බලා වැඩ කර තිබුණත්, දැන් ඒ ගැන ලොකු මතකයක් නැත. කෙසේ වෙතත්, ඔබ දැනටමත් ෆයිල් වර්ග කිහිපයක් සමඟ මෙටාඩේටා ලබා ගන්නට දන්න නිසා ඔබටම අවබෝධ වී ඇති පොදුවේ සෑම ෆයිල් වර්ගයකම මෙටාඩේටා සටහන් වන්නේ සමාන ආකාරවලට බව. පීඑන්ජීවල එම දත්ත පවතින ආකාරය ගැන ලස්සනට පහත වෙබ්පිටුවල විස්තර කර තිබෙනවා මා දුටුවා ගූගල් කළ විට.
