Math.prototype的值为()
举一反三
- Math对象的原型对象是 A: Math.prototype B: Function.prototype C: Object D: Object.prototype
- 表达式eval('''______ ('math').sqrt(3**2+4**2)''')的值为______ 。(5.0)
- 【多选题】Why do we prototype? ( ) A. We prototype to learn. B. We prototype to solve disagreements. C. We prototype to start a conversation. D. We prototype to fail quickly and cheaply.
- 假设math标准库已导入,那么表达式 eval('math.sqrt(4)') 的值为_________
- 先用“from math import *”语句导入math模块,输出表达式sqrt(2)*sqrt(2)==2的值时,发现其值为False,所以该表达式的更好的写法是 。设比较的精度为10-5
