Float to Printf structure

[MrVariable]

OK, I am writing a program that when you enter a number (23456.75) will then convert it to the appropriate text E.G:

Twenty Three Thousand Four Hundred and Fifty Six Pounds And Seventy Five Pence

I have got it working except with 11111.11 cos this returns:

Eleven thousand Ten One Pounds And Ten One Pence

Obviously a Major cock-up, The code i am using is massive cosisting of lots of case statements, printf, and if statements, any idesas on a much easier way that wil work?

I think much easyer will be if you transform your float to a string and process characters.

Here's a little something I just scribbled.
The only poor thing about it is it's overuse of the word 'and' for very large numbers.

Eg.

Enter num > 1234567
1234567 = one million and two hundred and thirty four thousand and five hundred and sixty seven

Hopefully, it will provide some inspiration for you
