## Discount calculation

.
This calculator allows you to calculate the discounted value of a quantity, but it also does the reverse calculation, ie,
the calculation of the price without discount from the discounted price.
We can also calculate the discount percentage from the discounted and undiscounted amounts.

The equations used are as follows:

Discount (%) = (price without discount-Price with discount) / Price without discount x 100

or, in other words

*Discount (%) = ( 1- (Price with discount / Price without discount )) x 100*
From this simple formula we can also obtain the following two:

*Price with discount = Price without discount x (1 - Discount(%)/100 ) *
*Non-discounted price = Discounted price / (1 - Discount(%)/100 ) *
