How to format real number?

[Brother Bill]

Where is the documentation for the equivalent of sprintf (C) or print a number as a decimal with 10 digits of precision?

I wrote a printf library that might interest you.  It's a bit long in the tooth, but I like it 🙂 It's void-safe and quite a bit more expressive (imho) than the C family versions.

Greetings rfo,  This failed to compile on AEL_PF_FORMAT.list_arg_out (ael_printf) 1014, 31.
It looks really good.  I'll use it once it compiles and runs on Eiffel 23.09
See attachment for sample project.

I'll have a look.  I've been using version 22 for a while.  I'll try with the newer version.  Thanks
