Explicitly converts an expression from one data type to the long data type.
CLng( expression )
This function explicitly controls the data type of a numeric expression. This
function forces integer arithmetic in cases in which currency,
single-precision, or double-precision arithmetic normally would occur. Because CLng converts expressions to integers, you can use this function to round
CLng converts each Single value to a Long. Note that 25427.45 is rounded down to
25427, whereas 25427.55 is rounded up to 25428.
X = CLng( 25427.45 )
