问题描述
当我尝试使用 float
作为模板参数时,编译器为这段代码哭泣,而 int
工作正常.
When I try to use float
as a template parameter, the compiler cries for this code, while int
works fine.
是不是因为我不能使用 float
作为模板参数?
Is it because I cannot use float
as a template parameter?
错误:
我正在阅读 Ron Penton 的 游戏程序员的数据结构",作者传递了一个 float
,但是当我尝试它时,它似乎无法编译.
I am reading "Data Structures for Game Programmers" by Ron Penton, the author passes a float
, but when I try it it doesn't seem to compile.
推荐答案
当前的 C++ 标准不允许将 float
(即实数)或字符串字面量用作 模板非- 类型参数.您当然可以使用 float
和 char *
类型作为普通参数.
The current C++ standard does not allow float
(i.e. real number) or character string literals to be used as template non-type parameters. You can of course use the float
and char *
types as normal arguments.
也许作者使用的编译器不符合当前标准?
Perhaps the author is using a compiler that doesn't follow the current standard?
