This is my Custom Function and I want to edit it


You'll probably want to fiddle with this a bit to get commas only in the integer part of the number (to the left of the decimal point).

After posting the above comment about the decimal part of the number (not intended to have commas inserted in it), I decided to take a shot at it myself. Here's what I came up with (calling fukky's AddComma function to deal with the integral part of the number):



Let ( [
PureNumber = GetAsNumber ( ANumber );
IntegralPart = Int ( PureNumber );
DecimalPart = PureNumber - IntegralPart
] ;

AddComma ( IntegralPart; DigitGroup ) &
If ( DecimalPart > 0; GetAsText ( DecimalPart ); "" )
