Hi,
After formatting some floating point values with “%8.4f” format, i got the following strings :
0.0000
123.0000
123.4500
123.0450
123.4560
Now, I want to remove trailing zeros and replace them with spaces to keep dot alignment, giving :
Case 1:
0.0
123.0
123.45
123.045
123.456
or, with integer display when appropriate
Case 2:
0
123
123.45
123.045
123.456
Currently, I came up with the following regex for case 2
("%8.4f" % x).gsub(/\.?0*$/) { |c| " " * c.size }
Still searching for a concise solution for case 1 !
Any ideas ?
