While Int appears to imitate Trunc, in that it returns the integer portion of a decimal number X, its behaviour is slightly different, as the result from an Int function is a data type from the floating-point family, rather than an integer type.

Please review Trunc for more information.

Also refer to Frac to return the fractional part of a decimal number.

Declaration:     Function Int(const X: Extended): Extended 

A few examples are shown below.

Procedure OnMapEvent(var Value:variant);
var bNumber : extended;
begin
Value := Int(5566.234589); // returns 5566
Value := Int(-8112.46); // returns -8112
bNumber := Int(4567.234589); // returns 4567
LogInfo(FloatToStr(bNumber));
bNumber := Int(-5232.46); // returns -5232
LogInfo(FloatToStr(bNumber));
bNumber := Int(1234.56); // returns 1234
LogInfo(FloatToStr(bNumber));
 
end;
