講解對象：math 模塊、cmath 模塊-數(shù)學(xué)模塊--python作者：融水公子 rsgz理解：math 模塊、cmath 模塊0.1 Python math 模塊提供了許多對浮點數(shù)的數(shù)學(xué)運算函數(shù)。0.2 Python cmath 模塊包含了一些用于復(fù)數(shù)運算的函數(shù)。0.3 cmath 模塊的函數(shù)跟 math 模塊函數(shù)基本一致，區(qū)別是 cmath 模塊運算的是復(fù)數(shù)，math 模塊運算的是數(shù)學(xué)運算。看看math包含的內(nèi)容>>> import math>>> dir(math)['__doc__','__file__','__loader__','__name__','__package__','__spec__','acos','acosh','asin','asinh','atan','atan2','atanh','ceil','copysign','cos','cosh','degrees','e','erf','erfc','exp','expm1','fabs','factorial','floor','fmod','frexp','fsum','gamma','gcd','hypot','inf','isclose','isfinite','isinf','isnan','ldexp','lgamma','log','log10','log1p','log2','modf','nan','pi','pow','radians','sin','sinh','sqrt','tan','tanh','tau','trunc']>>>看看cmath包含的內(nèi)容：>>> import cmath>>> dir(cmath)['__doc__','__file__','__loader__','__name__','__package__','__spec__','acos','acosh','asin','asinh','atan','atanh','cos','cosh','e','exp','inf','infj','isclose','isfinite','isinf','isnan','log','log10','nan','nanj','phase','pi','polar','rect','sin','sinh','sqrt','tan','tanh','tau']>>>看看實例：>>> import cmath>>> cmath.sqrt(-1)1j>>> cmath.sqrt(9)(3+0j)>>> cmath.sin(1)(0.8414709848078965+0j)>>> cmath.log10(100)(2+0j)>>>分享知識，分享快樂！希望中國站在編程之巔！----融水公子
