    Smile decimal points

    how could you output a number into a edit box that has as many decimal points as the number and cuts off the remainder at four places past the decimal point. EX

    If I understand correctly, write a filter for numbers with zeros then print into string.

    ie
    if(((fNumber*100)%10==0)&&((fNumber*1000)%100==0)& &.......)
    sprintf(sBuffer,"04.0f",fNumber);
    else
    sprintf(sBuffer,"%04.4f",fNumber);
    SetDlgItemText(GetDlgItem(hDlg,IDC_EDIT),sBuffer);
    (you get the idea)
