以10为底的对数 类似地,我们可以使用math模块的log10函数来计算以10为底的对数。 import math 计算以10为底的对数 result = math.log10(100) print("The base-10 logarithm of 100 is:", result) 通用对数函数 除了上述特定的对数函数外,Python还提供了一个通用的对数函数log(x, base),它允许你指定任意正...
什么是日志(Logarithm)? 日志是数学中的一个重要概念,反映了指数与其底数之间的关系。简单来说,给定一个底数 ( b ) 和一个数 ( x ),如果存在一个数 ( y ),使得 ( b^y = x ),那么就可以表示为: [ y = \log_b(x) ] 在这里,( b ) 通常取2(以二为底的对数)、10(以十为底的对数)、或 (...
