When rounding midpoint values, the rounding algorithm performs an equality test. Because of problems of binary representation and precision in the floating-point format, the value returned by the method can be unexpected. For more information, see Rounding and precision. See also Ceiling(Double) Fl...

The determinant of a square matrix provides a useful test for invertibility: it is zero exactly when the matrix isnotinvertible. The determinant of the identity is one, exchanging rows (or columns) changes the sign of the determinant, and the determinant is linear ineach separate row and colum...
we would all write our own test for the material. We would also write a complete answer key for it. We would then take one exam each of the next successive days. By the time the actual in class test rolled around, we already had completed three other tests and reviewed them. Once I...
