fortran - FORTRAN 77除以零行为(FORTRAN 77 Divide By Zero Behavior)

Question

I am working on re-engineering an old FORTRAN77 program to Python for a while now.

(我正在一段时间内将旧的FORTRAN77程序重新设计为Python。)

I'm running into an issue, though: when dividing by zero, it appears that the FORTRAN program just continues processing the data without issue.

(不过，我遇到了一个问题：当被零除时，似乎FORTRAN程序只是继续处理数据而没有问题。)

However, predictably it causes an issue in Python.

(但是，可以预料的是，这会在Python中引起问题。)

I'm not able to find a discussion about this on any official channel for F77, and I only have an old version of the source code for the program I am translating that I can't get to compile.

(我无法在F77的任何官方频道上找到有关此问题的讨论，并且我只有正在翻译的程序的旧版本源代码，无法编译。)

TL;DR: How does F77 handle division by zero for the following cases?:

(TL; DR：在以下情况下，F77如何处理被零除？：)

1. REAL division

   (房地产部)

2. INT division

   (INT部门)

3. The numerator is also zero (eg 0./0.)

   (分子也是零（例如0./0。）)
