在DELPHI中如何将实数型转换成整型？用的是哪一个函数？

[shinesi]

round()

[naughtyboy]

trunc()取整
round()四舍五入

[debussy]

unction Trunc(X: Extended): Int64;

Description

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 value of X is not within the Int64 range, an EInvalidOp exception is raised.

[chutian]

function Round(const X: Extended): Extended;
var
I: Double;
begin
Result := Int(X);
I := Frac(X);
if I >= 0.5 then
Result := Result + 1;
end

不是可以强制进行数据类型转换吗？？
