The float type in Python designates floating-point numbers. To create these types of numbers, you can also use literals, similar to what you use in math. However, in Python, the dot character (.) is what you must use to create floating-point literals:...
>>> math.pow(2, 3) 8.0 >>> 2 ** 3 81234 math.sqrt(x)**。求x的平方根。 >>> math.sqrt(4) 2.0 >>> math.sqrt(9.0) 3.01234 开根号。Python的math库中只有开平方根,没有立方根和n次方根,不过可以利用math.pow或者**,只需把根号变成分数。 >>> math.pow(4, 1.0 / 2) //平方根,相当...

【1】math.isfinite():是数学模块的库方法,用于检查给定数是否为有限数,它接受数字(整数/浮点数,有限,无限或NaN)。如果 number 是有限数字(或可转换为有限数字),那么返回 true。否则,如果 number 是 NaN(非数字),或者是正、负无穷大的数,则返回 false。 【2】np.nan:表示not a number 【3】np.inf :表示...
