Sale price = $32
Buyer fee = $5
Author fee = 23.75%
Author earning = (Sale price - Buyer fee)*((100-Author fee)/100)
so
Author earning:
$32-$5=$27
$27 * 0.7625=$20.5875
We must round it to $20.59 not $20.58.
But Envato rounds it to $20.58.
This is not valid in mathematical perspective and not ethical I think.
