Help with Converting Formula in C to vb.net

Question

User1958078207 posted

Please help.  I am reproducing a program written in C to vb.net and I am getting different results on a math formula.  I am sure it is something simple that I am overlooking.

Here is the formula in C

num = (10 * 9 * 80900 * 0501) & 0xffff;

Here is the same formula in vb.net

num = (10 * 9 * 80900 * 0501) AND &HFF

Results in C: (10 * 9 * 80900 * 0501) & 0xffff = 56168

Results in vb.net : (10 * 9 * 80900 * 0501) AND &HFF = 47240

"0501" in C is an octal literal - the VB equivalent is "&O501":

num = (10 * 9 * 80900 * &O501) And &Hffff
