This should work for all decimal numbers in PB.

decimal dec_num
string invariant_string

string first_part
string second_part

dec_num= 1.23456

first_part = string( truncate( dec_num, 0 ) )
second_part = mid ( string( abs( dec_num - truncate( dec_num, 0 ) ), '0.############################' ), 3 )

invariant_string =  first_part
if len(second_part) > 0 then
	invariant_string = invariant_string + '.' + second_part
end if
//if you want to display "x.0" if the decimal part is zero, replace the mask for second_part with
//0.0########################### and just do this instead:

// invariant_string = first_part + '.' + second_part

Edit: added an abs() for the decimal part to make it work for negative numbers

Decimal ldec_decimal
Long ll_number
String ls_number, ls_decimal, ls_whole, ls_display

ldec_decimal = 1234.56

ll_number = ldec_decimal * 100
ls_number = String(ll_number)
ls_decimal = Right(ls_number, 2)
ls_whole = Left(ls_number, Len(ls_number) - 2)
ls_display = ls_whole + "." + ls_decimal

MessageBox("Decimal", ls_display)

Hi David

If your suggestion worked it would be an error. Formats format to regional strings and I think this is correct.

I tried messagebox("test",string(3.14, '0.00')) and the result was:

---------------------------
test
---------------------------
3,14
---------------------------
OK   
---------------------------

I know there is a few special parameters to string() like "address" so I'm wondering if there's no string ( 3.14 , "invariant" ) alternative.

Hi Tomas

you could try string(ld_decimal, '0.00')
