If the above approximation for pow is not good enough, you can still try to replace it with exponential functions, depending on your machine and compiler this might be faster: x^y = e^ (y*ln (x)) And the result: e^ (z * x^y) = e^ (z * e^ (y*ln (x))) Another trick is when some parameters of the formula do not change often. body armor strawberry banana ingredientsclone a power appWeb以下是 fabs () 方法的语法: import math math.fabs( x ) 注意： fabs ()是不能直接访问的，需要导入 math 模块，通过静态对象调用该方法。 参数 x -- 数值表达式。 返回值 以浮点数形式返回数字的绝对值。 实例 以下展示了使用 fabs () 方法的实例： 实例 1 #!/usr/bin/python # -*- coding: UTF-8 -*- import math x = -1.5 y = math.fabs(x) print(y) # 输出 1.5 x = 10 y = … clone angular project from github and run
