2. 使用异常处理机制 Python 提供了异常处理机制,可以用try...except来捕获和处理浮点数错误。 代码语言:javascript 代码运行次数:0 运行 AI代码解释 try:result=a/b except FloatingPointErrorase:print(f"浮点数异常:{e}") 通过这种方式,我们能够优雅地捕捉异常并处理。 3. 控制溢出和下溢 溢出和下溢可以通过...
@文心快码floating-point exception - erroneous arithmetic operation. 文心快码 浮点异常(Floating-Point Exception)详解 1. 解释什么是浮点异常(Floating-Point Exception) 浮点异常是指在计算机程序执行过程中,由于浮点运算的某些特殊情况而导致的异常或错误。这种异常通常发生在进行浮点数计算时,遇到了无法处理或不合法...
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
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 ...
-p precision: precision of the floating-point arithmetic, works only with-f mpfr. -f dd: sets the floating-point type to double-double. -f qd: sets the floating-point type to quad-double. -f dpe: sets the floating-point type to DPE (default ifm=heuristic). ...
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 arithmetic is considered an esoteric subject by many people. This is rather surprising because floating-point is ubiquitous in computer systems. Almost every language has a floating-point datatype; computers from PCs to supercomputers have floating-point accelerators; most compilers will ...
