Division in Java vs. VB
Division is performed differently in Java and VB. Java, like other C-based languages truncates the division result when both operands are integer literals or integer variables (or integer constants). In VB, you must use the integer division operator (\) to get a similar result.
e.g.,
Java:
double d = 5 / 3; //assigns 1 to d (truncated since both operands are integers)
VB - Option Strict On:
Dim d As Double = 5 / 3 'assigns 1.666... to d
Dim d As Double = 5 \ 3 'assigns 1 to d
VB - Option Strict Off:
With Option Strict Off in VB, the results can be confusing. In the following example, contrary to what you might expect, 1 is not produced in both cases:
Dim d As Double = 5.4 \ 3 'assigns 1 to d
Dim d As Double = 5.6 \ 3 'assigns 2 to d
With Option Strict Off, VB first rounds the integer division operands (the first case rounds 5.4 to 5 and the second rounds 5.6 to 6), before truncating the division result. With Option Strict On, this would not compile.
