Rounds a floating point number to an integer System unit
 function Round(const Number Extended):Int64;
The Round function rounds a floating point Number to an Integer value.
The rounding uses Bankers rules, where an exact half value causes a rounding to an even number:
12.4 rounds to  12
12.5 rounds to  12 // Round down to even
12.6 rounds to  13
13.4 rounds to  13
13.5 rounds to  14 // Round up to even
13.6 rounds to  14
The Trunc function does the same, but returns the integer in an Integer value.
