Round (function)

Rounds a Real-type value to an Integer-type value.
Declaration:
function Round(X: Real): Longint;

Remarks:
X is a real-type expression. Round returns a Longint value that is the value of X rounded to the nearest whole number. If X is exactly halfway between two whole numbers, the result is the number with the greatest absolute magnitude. A run-time error occurs if the rounded value of X is not within the Longint range.
