在这篇文章中,我们将展示如何在Python中表示一个 无限大 的数。无穷大 是一个未定义的数字,可以为正数也可以为负数。一个数字用来表示无穷大,两个数字值的和可以是一个数值,但是可能具有不同的模式;它可能具有负值或正值。对于无限大数值的所有算术运算,无论加法、减法、乘法或其他任何操作,结果始终为一个无限大...
NaN(not a number)数 如果一个数超出infinite,那就是一个NaN(not a number)数。在NaN数中,它的exponent部分为可表达的最大值,即FF(单精度)、7FF(双精度)和7FFF(扩展双精度)。 NaN数与infinite数的区别是:infinite数的significand部分为0值(扩展双精度的bit63位为1)。而NaN数的significand部分不为0值。 Na...
floor(number) rounded_up = math.ceil(number) print(rounded_down) # 输出: 7 print(rounded_up) # 输出: 8 # 检查数字是否为有限数、无穷大或NaN finite_number = 10 infinite_number = float('inf') nan_number = float('nan') print(math.isfinite(finite_number)) # 输出: True print(math....

Pi is an irrational number, which means it can’t be expressed as a simple fraction. Therefore, pi has an infinite number of decimal places, but it can be approximated as 22/7, or 3.141.Interesting Fact: Pi is the most recognized and well-known mathematical constant in the world. It ...
exponent. The “math.pow()” function takes two parameter values, base and exponent. The function returns “ValueErrors” when the base number value is less than “zero” and the exponent value is “float”. The infinite base or exponent number has returned the infinite number in the output...
我们偶尔会在别人代码里面看到Python里面有个inf,这是干啥的呢. inf代表infinite,表示无限,亦即我们高中学过的__无穷__.inf分为正无穷inf或+inf和负无穷-infPython中的表示方法是float('inf')和float('-inf') 环境 Python3.8 测试 把常规的运算和比较都测试一遍+ - \\* / % // > == < !=,结果我就...
