小弟是使用BCB 6.0,目前需使用一變數,.存放值為幾百萬的數值,但試過long 型態,還是不夠用,請問需宣告為何種
型態或該如何解決才有用??? 多謝!!!!

Type	Bytes	Range (signed)	Range (unsigned)	Literals
bool	1	0..1		false, true
char	1	-128.. 127	0..255	'a'
short	2	-32,768.. 32,767	0..65,535	none
int	4	-2,147,483,648.. 2,147,483,647	0..4,294,967,295	23, 0xAF
long	4	-2,147,483,648.. 2,147,483,647	0..4,294,967,295	23L, 0xAFL

Floating-point Types

<!--====================== Floating-point Types --> The floating-point types, float and double, are usually stored in IEE-754 format. Calculations may produce NaN (Not a Number); or positive or negative infinity.

Type	Bytes	Range	Accuracy	Literals
float	4	-3.4E38.. 3.4E38	6-7 digits	3.14F 6.02e23F
double	8	-1.7E308.. 1.7E308	14-15 digits	3.14 6.02e23
long double	12	??-??	?? digits

Operators: arithmetic, comparison, assignment.

如果long不夠，double就足夠了吧！？
還有你以前提的有些問題，也有正確的答案了，不要吝嗇結案！

thanks 大大,我忘了按結案,感恩!!!!!
