Vat Accounting does not match

Vat Accounting does not match

My supplier sells his products inclusive of Vat. The total of my purchase is 1,882 tax inclusive. But the Vat (which is of 5%) comes out to be 89.63 rather than 89.62. Tax inclusive works by adding the tax and the amount and the total is what you pay. in this case. the vat multiplied by 21 should give the total. but the vat is calculated wrong. 1882/21 gives 89.6190 . How does your accounting software round this number up to 89.63? Fix this quick.
