Trunc removes any decimals and returns aValue truncated to its own integer value.  

Minus (negative) signs are accepted and also returned, but separating commas and any other non-numeric characters must be stripped out before being passed into the Trunc function.

Trunc performs a similar function to Int. However, Int returns a floating-point number. Please refer to Int for more information.

Also refer to the Round series of functions, for a function that rounds decimals up and/or down. 

Declaration:   Function Trunc( aValue : Extended) : Integer

Several examples follow.

Procedure OnMapEvent(var Value:variant);
var aNumber : integer;
begin
Value := Trunc(19.234589); // returns 19
Value := Trunc(-75339.46); // returns -75339
aNumber := Trunc(4567.234589); // returns 4567
LogInfo(IntToStr(aNumber));
aNumber := Trunc(-5232.46); // returns -5232
LogInfo(IntToStr(aNumber));
aNumber := Trunc(1234.56); // returns 1234
LogInfo(IntToStr(aNumber));
end;
