我不禁要想出一种只能以愤怒价值表示的方式。
如何获得惯性价值标识?
请您提供帮助。
我希望的是
int value = 100; ====> result : 1
int value = -100; ====> result : -1
int value = 0; ====> result : 0

Trivial。
int signum(int n) { return (n < 0) ? -1 : (n > 0) ? +1 : 0; }

(int)signOfInteger:(int)integer {
return (integer > 0) - (integer < 0);
}
- (int)signOfInteger:(int)integer {
if (integer != 0) {
integer = (integer < 0) ? -1 : +1;
}
return integer;
}
signOfIntegerOrFloat = (x-fabs (x)) > 0.0 ? 1 : ((x-fabs(x)) < 0.0 ? -1:0
float = fabsf ( float ) - for float
