math数学模块是python3的标准库,下面讲一下math模块里的方法以及应用。
一、数学函数
math. ceil(x)取大于等于x的最小的整数值,如果x是一个整数,则返回x取大于等于x的最小的整数值,如果x是一个整数,则返回x
math. copysign ( x , y )把y的正负号加到x前面,可以使用0把y的正负号加到x前面,可以使用0把y的正负号加到x前面,可以使用0
math. fabs ( x )
math. factorial ( x )
math. floor ( x )
math. fmod ( x , y )
math. frexp ( x )
math. fsum ( iterable )
math. gcd ( a , b )
math. isclose ( a , b , * , rel_tol=1e-09 , abs_tol=0.0 )
math. isfinite ( x )
math. isinf ( x )
math. isnan ( x )
math. ldexp ( x , i )
math. modf ( x )
math. remainder ( x , y )
math. trunc ( x )
二、幂函数和对数函数
math. exp ( x )
math. expm1 ( x )
math. log ( x [, base ])
math. log1p ( x )
math. log2 ( x )
math. log10 ( x )
math. pow ( x , y )
math. sqrt ( x )
三、三角函数
math. acos ( x )
math. asin ( x )
math. atan ( x )
math. atan2 ( y , x )
math. cos ( x )
math. hypot ( x , y )
math. sin ( x )
math. tan ( x )
math. degrees ( x )
math. radians ( x )
math. acosh ( x )
math. asinh ( x )
math. atanh ( x )
math. cosh ( x )
math. sinh ( x )
math. tanh ( x )
四、特殊函数
math. erf ( x )
math. erfc ( x )
math. gamma ( x )
math. lgamma ( x )
五、常量
math. pi π = 3.141592…
math. e e = 2.718281…
math. tau τ = 6.283185…
math. inf
math. nan
