Although there are many integers from 0 to $2^{23}-1$, the number is ultimatelylimited to, which is just as many as $2^{32}$; but floating-point numbers are different, we can Think of it this way: There are only ten integers in the range from 1 to 10, but there areinfinitely ...
如果用四舍五入就没问题了 为什么有了保护位,精度反而下降了? 保护位保护的是652.0和7.4765625这里面的数字,而未必是原来数字的精度

Floating-point arithmetic in Python can be imprecise. As a word of caution, never use floating point numbers to represent quantities that need to be strictly accurate, such as money. To do math with money in Python, for example, it is customary to work with cents, rather than full dollars...
Thebigfloatpackage is a Python package providing arbitrary-precision correctly-rounded binary floating-point arithmetic. It is implemented as aCythonwrapper around theGNU MPFR library. A couple of lines of Python code should give the idea:
Floating Point MathYour language isn't broken, it's doing floating point math. Computers can only natively store integers, so they need so...
🚨 FloatingPointError: Floating Point Exception 完美解决方法 🚨 摘要 大家好,我是默语,一位专注于全栈开发、运维和人工智能技术的博主。在今天的博客中,我们将深入探讨 FloatingPointError: floating point exception 的产生原因及其解决方案。这是Python和其他语言中处理浮点数运算时常见的问题,导致代码意外终止。
