C++ cmath log2() function❮ Math Functions ExampleReturn the base 2 logarithm of different numbers:cout << log2(64.0); cout << log2(10.0f); cout << log2(3.1623); cout << log2(1.0); cout << log2(0.0f); cout << log2(-1.0f); ...
成功后,函数返回x的 base-2 日志。 否则,这些函数可能会返回以下值之一: 问题返回值 x< 0NaN x= ±0-INFINITY x= 10+ +INFINITY+INFINITY NaNNaN 域错误NaN 极点错误-HUGE_VAL、-HUGE_VALF或 -HUGE_VALL 按_matherr中所指定的内容报告错误。
如果成功,則傳回 (+ 1) 的自然 (base-e) 記錄x。 否則,可能會傳回下列其中一個值: 輸入結果SEH 例外狀況errno +INF+INF 非正規數與輸入相同UNDERFLOW ±0與輸入相同 -1-INFDIVBYZEROERANGE < -1NaNINVALIDEDOM -INFNaNINVALIDEDOM ±SNaN與輸入相同INVALID ...
