(1) There is a confusion in the compiler whether to convert (_CurrentPageIndex / _PageButtonCount) to double or to decimal, since floor can take both double and decimal
You can help/hint the compiler by casting either _CurrentPageIndex or _PageButtonCount to a double or decimal
(2) the result is an expression of type double or decimal. Assigning that to an int results in a loss of precision. The compiler does not do that for you. Hence you have to cast it to an int
StartLoop = (int)(Math.Floor((double)_CurrentPageIndex / _PageButtonCount) * _PageButtonCount) + 1;
But maybe this does what you're after also
Since CurrentPageIndex and PageButtonCount are int, the result is an integer division with no remainder
[ remember - this is not foxpro ]
StartLoop = (_CurrentPageIndex / _PageButtonCount) * _PageButtonCount + 1;
