Werner, As you say, would be good in the core, but almost as good is a simple macro.
See attached and import to any wiki, then open $:/PSaT/format-numbers <https://tiddlywiki.com/#%24%3A%2FPSaT%2Fformat-numbers> For instructions Syntax <<format-number n [t] [d] [p]>> - *n* is the number with or without decimal places (no default)*t* is the thousands separator (optional) - defaults to "," - (Can change default in format-number macro, set thousands-separator) - *d* is the decimal separator (optional) - defaults to "." - (Can change default in format-number macro, set decimal-separator) - *p* is the decimal places to use (optional) - defaults to "2" - (Can change default in format-number macro, set decimal-places) For example <<format-number 1234567654321.6666>> results in 1, <#%2C>234, <#%2C>567, <#%2C>654, <#%2C>321.67 *$:/PSaT/format-numbers/macro* \define format-number(n t d p) <$set name=thousands-separator value="$t$" emptyValue=","> <$set name=decimal-separator value="$d$" emptyValue="."> <$set name=decimal-places value="$p$" emptyValue="2"> <$set name=fixed-decimal value={{{ [[$n$]fixed<decimal-places>] }}}> <$set name=integer value={{{ [<fixed-decimal>split[.]first[]] }}}> <$set name=remainder value={{{ [<fixed-decimal>split[.]last[]] }}}> <$set name=length filter="[<integer>length[]]"> <$macrocall $name=each-digit length=<<length>> /><$list filter="[<decimal-places>!match[0]]" variable=nul><<decimal-separator>><<remainder>></$list> </$set></$set></$set></$set></$set></$set></$set> \end \define each-digit(length) \whitespace trim <$list filter="[range[1,$length$]]" variable=position> <$set name=digit filter="[[$(integer)$]split[]nth<position>]"> <$set name=zeros filter="[[$length$]subtract<position>]"> <<digit>>{{{ [<zeros>!match[0]remainder[3]match[0]then<thousands-separator>] }}} </$set></$set> </$list> \end *Regards* *Tones* On Friday, 18 September 2020 at 23:20:14 UTC+10 Werner wrote: > Tony, > > sorry, was absorbed by other projects, so couldn't reply earlier.
