Hello -
I need to display the long forms of numbers read from a database table
without scientific notation.
For example, a number read as 1.5e-6 should be displayed as “0.0000015”,
and so on.
Is there an easy way to do this in ruby, or do I need to write a
function to do it? I was thinking about using a lot of
number.to_s.split…
Thanks!

Use a formatted print statement.
printf(“%.7f\n”, 0.0000015)
You will need to adjust the first parameter to taste.
You can read about string formatting at your command line with: ri
Kernel.sprintf
There is also an alternative syntax, see: ri String.%
