Decimal Multiplier Problem

This might be simple but I don't know why it doesnt work.
  
Decimal pricePerPerson = 100.00;
Decimal sellPerPerson = 1.1764705882352 * pricePerPerson;
sellPerPerson = sellPerPerson.setScale(2);
This returns 117.65 as expectd.

However this... 
Integer discountPercent = 15;
Decimal pricePerPerson = 100.00;
Decimal sellPerPerson = (100/(100-discountPercent)) * pricePerPerson;
sellPerPerson = sellPerPerson.setScale(2);
returns 100.00 and I'm not sure why. It should also return 117.65

Hi joe,

As discountPercent is declared as Integer so (100/(100-discountPercent)) is returning Integer Value which is 1 and it is multipled with 100.00 gives you 100.00.

Instead of that define discountPercent as decimal then you will get required result.

Let me know if you face any issues.

If this solution helps, Please mark it as best answer.

Thanks,

Setting discountPercent as decimal rather than Integer has worked. Thanks
