Issue
I want to output floating numbers with exact number of digits without padding in the front, since I want to prepend $ sign
For example I read numbers:
1.2345
12.345
123.456
and I want output:
$1.23450
$12.3450
$123.456
I tried many different variations in printf but can't fix number of total digits. I also didn't find answer to this particular problem
printf "$%.7f\n" 1.2345 12.345 123.456
neither with "$%.7f\n "$%07f\n "$%6.4f\n "$%.7g\n
Do I need to get different formatting for for different magnitude of numbers ie 1, 10, 100?
Solution
How to printf fixed number or digits in floating in bash
Print first 7 characters from the printed number.
printf '$%.7s\n' "$(printf '%.6f' 1234.2345)"
Do I need to get different formatting for for different magnitude of numbers ie 1, 10, 100?
Yes, you should implement your own formatting function for custom formatting requirements. There is no such printf formatting specifier for what you want.
