[RESOLVED] Single Variable Type - odd amount?

[Static]

Dim Bal As Single = SumOfCash - (CashSales + StartAmt)

SumOfCash = 272.85
CashSales = 122.85
StartAmt = 150.00

Bal = .00000725 ???

so.. Bal <> 0 when it should be...

Any ideas?

I solved the issue by using Math.round but i am curious as to what could cause it?

Dim Bal As Single = Math.Round(SumOfCash - (CashSales + StartAmt), 2)
