How to convert numeric amount into words from X++

Here's the code :)

display TempStr total_txt()
{
    PayrollPayTypeAmount           NetAmount; 

    Str                            TextValue;  

    ;

    NetAmount  =  PayrollPaySlipJour.DispNet ;

    TextValue  =  global::numeralsToTxt(NetAmount);

    return substr(TextValue, 5, strlen(TextValue)-4);
}

Happy daxing!
