skip decimal point when 0 decimal digits are requested

[alusiani]

When no decimal digits are requested, no decimal digits are formatted, but the decimal point is still included. This is different from printf in C and from format in Python, which omit the decimal point in this case.

Example in Python:

"{:.0f}".format(123.4)
## result: '123'

Example in Julia

using Formatting
fmt(".0f", 123.4)
## result: "123."
format("{:.0f}", 123.4)
## result: "123."

Would it be possible to change this behaviour and make it the same as C printf() and Python format()?

I second this request!
This discrepancy has led to nasty bugs in a workflow of mine that combines Python and Julia scripts.

Note: this has been fixed (for several years) in Format.jl
