How to format amounts

This doc specifies the different types of formatting amounts inside the Safe apps.

Full amount

Used when the entire amount matters.

• No truncation, always show all numbers.
• Thousands and decimal separators are used according to user's locale.

Short amount

Used in cases where horizontal screen real estate is limited and the complete amount is not super important.

• Cut off after the 5th decimal, no matter how many decimals there are: 0.12345
• Remove trailing zeroes, i.e. display 0.10000 as 0.1
• Use the 5 decimals up until 999.99999
• Use 1 decimal less from 1,000.0001 until 9,999.9999 (Use comma as thousands-separator)
• Use 1 decimal less from 10,000.001 until 99,999.999
• Use 1 decimal less from 100,000.01 until 999,999.99
• Use 1 decimal less from 1,000,000.1 until 9,999,999.9
• From 10,000,000 No Decimals until 99,999,999
• Then Use 10.001M until 999.999M
• Then 1.001B until 999.999B
• Then 1.001T until 999.999T
• Then just > 1000T
• Thousands and decimal separators are used according to user's locale.
• k, M, B, T should be localized.

This format has been discussed on a Github issue

Fiat numbers

The same rules from above apply to fiat numbers as well.
