Tore,
I think there is an error in that function:
? NTOC(0.2, 1) &&-> 0.2
? NTOC(0.2, 0) &&-> 0
* but
? NTOC(0.6, 1) &&-> 0.6
? NTOC(0.6, 1) &&-> 1

>FUNCTION NTOC && Numeric to character, trims the result, optional number of decimals)
>   PARAMETERS lnInData,lnDecimal
>   IF PCOUNT()=1
>      lnDecimal=0
>   ENDIF
>RETURN LTRIM(STR(lnInData,10,lnDecimal))
>ntoc(0.20,1)=0.2
>ntoc(0.20)=0
