Round(x)函数 四舍五入 定义:function Round(X: Real): Longint; 注意:X是实型表达式. Round 返回Longint型的X的四舍五入值.如果返回值超出了Longint的表示范围,则出错. 例子: 1 2 3 4 5 6 begin Writeln(2.4,' rounds to ', Round(2.4));{ 2 } Writeln(2.5,' r

System.Trunc、System.Round、System.Int - 返回整数部分 举例:vari: Integer; d: Real; begini := Trunc(1234.5678); {截取整数} ShowMessage(IntToStr(i)); {1234} i := Trunc(-1234.5678); ShowMessage(IntToStr(i)); {-1234} i := Round(1234.5678); {四舍五入} ShowMessage(IntToStr(i)); {...
delphi取整int和trunc区别 Delphi syntax:function Trunc(X: Extended): Int64;Description InDelphicode, the Trunc function truncates a real-type value to an integer-type value. X is a real-type expression. Trunc returns an Int64 value that is the value of X rounded toward zero.If the truncated...
