Sorry but I must say a lot of people failed math including SE. 14% can not be use simply as the percentage form. Rules says we must convert that % sign to a decimal in order to use it with other similar numbers. Hence you get .14 and not .14%.

Then you can either do basic math or a more complicated step to solve. Either find what 625,000,000 is .14 and subtract or the other method.

Even with math done correctly SE failed display correct percentage for half. SE simply rounded up of 3.6m which that 400k makes a world of a difference in the current game economy.
