Round

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

Example:

Base Syntax

 var
   numberFloat : Float;
 
 begin
 
   numberFloat := 15.50;  
   ShowMessage('Round('+FloatToStr(numberFloat)+') = '+FloatToStr(Round(numberFloat)));
 
 end;

TRObject Syntax

 var
   numberFloat : Float;
 
 {
 
   numberFloat = 15.50;  
   ShowMessage('Round('+FloatToStr(numberFloat)+') = '+FloatToStr(Round(numberFloat)));
 
 }

Output:

Round(15,5) = 16
