Table 105 — Meaning of sign options [tab:format.sign]

🔗 Option	Meaning
🔗 +	Indicates that a sign should be used for both non-negative and negative numbers. The + sign is inserted before the output of to_chars for non-negative numbers other than negative zero. [Note 5: For negative numbers and negative zero the output of to_chars will already contain the sign so no additional transformation is performed. — end note]
🔗 -	Indicates that a sign should be used for negative numbers and negative zero only (this is the default behavior).
🔗 space	Indicates that a leading space should be used for non-negative numbers other than negative zero, and a minus sign for negative numbers and negative zero.
