 * – where does the ‘specific date’ come from?
    – do you need that for the front
   page, or for each post? – where does the ‘specific number’ come from? – ‘percent’
   of what?

 * Hello,
 * thank you for your answer.
 * – The specific date comes from my input.
    – I need it for several pages. – Specific
   number comes also from my input. – Output should be a simple number. With percentage
   I meant the sign after the number.
 * I hope you can help me.
 * Best regards,
    Ismar

 * Specifically, the aim is to calculate the return on investment.
    In the above
   example, after 10 days 10% of the initial investment is paid back (at 1% daily
   interest).
