<p>What is the difference in ASP/VBScript between <code>Int()</code> and <code>CInt()</code>?</p>

Int()
The Int function returns the integer part of a specified number.
CInt()
The CInt function converts an expression to type Integer.
And the best answer comes from
MSDN
CInt differs from the Fix and Int functions, which truncate, rather than round, the fractional part of a number. When the fractional part is exactly 0.5, the CInt function always rounds it to the nearest even number. For example, 0.5 rounds to 0, and 1.5 rounds to 2.
