因此
float x = x + 0.25;
每当发生点击时,该浮标就会被称作。
NS Carlo(@%f),x
我只想把那部分数字回来。
x return
1.25 1
1.50 1
3.25 3
4.75 4
任何想法?

如果浮动点号码不在<代码>int的范围之内,则转至int
。
印刷%.0f”
.n truncate, 编号4.75, 将作为5<>。
如果您的汇编者(更准确地说,您的运行时间图书馆)支持他们,则trunc(
,truncf(
)和truncl(
Function,在<math.h>
上,确实需要:
printf("%.0f
", trunc(x));
这些职能在99年是新的,因此,您的汇编者可能不支持这些职能。 C90的确提供了<代码>底线()功能;如果你为负数写了某些特别案例代码,你可以使用。
You can treat x as an int (cast):
NSLog("%d", (int)x);
注:这不会四舍五入,而是将价值缩减,只退回到ger。
EDIT:请指出,这并不是对所有可能的浮动价值进行分类的一种安全方法,它将通过(符合
