For 2023 (and 2024 ...) - we are now fully retired from IT training.
We have made many, many friends over 25 years of teaching about Python, Tcl, Perl, PHP, Lua, Java, C and C++ - and MySQL, Linux and Solaris/SunOS too. Our training notes are now very much out of date, but due to upward compatability most of our examples remain operational and even relevant ad you are welcome to make us if them "as seen" and at your own risk.

Lisa and I (Graham) now live in what was our training centre in Melksham - happy to meet with former delegates here - but do check ahead before coming round. We are far from inactive - rather, enjoying the times that we are retired but still healthy enough in mind and body to be active!

I am also active in many other area and still look after a lot of web sites - you can find an index ((here))
Outputting numbers as words - MySQL with Perl or PHP

Oracle's in_char function lets you convert numbers into a text string, but it's an unusual facility to have as as built-in; there's no such facility (as far as I know) in MySQL but you can get around this easily enough within your controlling application - the Nums2Words module on the CPAN (in Perl), and a similar module on the PEAR (for PHP users) does all the hard work for you.

Here's a Perl example:

use Nums2Words;
@testvals = (7, 12, 153, -19, 1234007, 0.7,
  3.1415, 666.62, -176.75, 10.6e15);
foreach $number(@testvals) {
  $t1 = ucfirst(lc(num2word($number)));
  print "$number = $t1\n";
  }


When you run that, you get

earth-wind-and-fire:~/jun07 grahamellis$ perl n2w
7 = Seven
12 = Twelve
153 = One hundred fifty-three
-19 = Negative nineteen
1234007 = One million, two hundred thirty-four thousand, seven
0.7 = Zero and seven tenths
3.1415 = Three and one thousand, four hundred fifteen ten-thousandths
666.62 = Six hundred sixty-six and sixty-two hundredths
-176.75 = Negative one hundred seventy-six and seventy-five hundredths
1.06e+16 = One and six thousand, sixteen millionths
earth-wind-and-fire:~/jun07 grahamellis$


A web search lead me to similar code in Java, and no doubt there's someting in the Cheeseshop if you're a Python programmer. Lesson to be learnt - look around before you re-write code!
