是否有可能找到在蟒蛇范围[a，b]随机浮动？ [英] is it possible to find random floats in range [a,b] in python?

问题描述

我尝试在[0.8,0.9]范围内的python随机浮点数生成，但不幸的是，我发现所有的工具只能在[a，b]范围内为浮点数生成随机数。 （如 Random.uniform（a，b））

同时，我尝试了这样的操作： p>

  uniform（0.8,0.90000000001）
  

但是那真的很坏

有什么想法？

解决方案

[0.8,0.9]和[0.8,0.9]之间的差异是微乎其微的。考虑到二进制浮点的局限性，我不认为这有什么区别，因为无论如何0.9都不能精确表示。使用[0.8,0.9）。

I'm trying to generate in python random floats in the range of [0.8,0.9] , but unfortanetly all the tools i found could only generate randoms in the range of [a,b) for floats. ( like Random.uniform(a,b) )

Meanwhile , I tried doing something like this :

uniform(0.8,0.90000000001)

but thats realy bad

any ideas ?

解决方案

The difference between [0.8, 0.9] and [0.8,0.9) is vanishingly small. Given the limitations of binary floating-point, I don't think there even is a difference, since 0.9 can't be precisely represented anyway. Use [0.8,0.9).
