Python | cmath.pi 常量 原文:https://www.geeksforgeeks.org/python-cmath-pi-constant/ 借助**cmath.pi**常数,我们可以在圆的面积、圆的周长等计算中使用这个常数值。 语法: cmath.pi 返回:返回圆周率值。 示例#1 : 在这个示例中,我们可以看到,通过使用cmath.pi常
cmath.pi The mathematical constant , as a float. 2 cmath.e The mathematical constant e,as a float. 3 cmath.inf Floating point positive infinity. Equivalent to float. 4 cmath.nan Floating point is not a number(NaN) value. This is Equivalent to float('nan'). 5 cmath.nanj This func...
cmath.cos(x)Returns the cosine of x cmath.cosh(x)Returns the hyperbolic cosine of x cmath.exp(x)Returns the value of Ex, where E is Euler's number (approximately 2.718281...), and x is the number passed to it cmath.isclose()Checks whether two values are close, or not ...
In case all else fails, simply addmath.hto your code. This is necessary because, as previously mentioned, you are using non-standard C/C++. Alternatively, as David mentioned in the comments, creating a constant to define the value would result in a more portable solution. Edit 2 of the o...
借助**cmath.tau**常数,我们可以在数学公式的计算中使用这个常数值。语法: cmath.tau 返回:返回τ值。示例#1 : 在这个示例中,我们可以看到,通过使用cmath.tau常数,我们能够非常容易地驱动数学公式。# importing cmath library import cmath # using cmath.pi constant gfg = cmath.tau * cmath.pi print(...
Here, we are calculating the probability density at a specified point "x" for a standard distribution using cmath.e constant.Open Compiler import cmath x = 2 mu = 0 sigma = 1 probability_density = (1 / (cmath.sqrt(2 * cmath.pi) * sigma)) * cmath.e ** (-0.5 * ((x - mu...
