IEEE floating-point exceptions in C++This page will answer the following questions.My program just printed out 1.#IND or 1.#INF (on Windows) or nan or inf (on Linux). What happened? How can I tell if a number is really a number and not a NaN or an infinity? How can I find out...
To preventfloating point exceptionsin C++, it is essential to check all the parameters passed to functions, to use appropriate formats and to explicitly test divisors for zero values. In addition, when using double data types, it is important to enlarge the range of the data type if the prog...

Dear All, I have a mixed cpp / fortran project and I want that (in debug mode) the program stops as soon as a floating point exception occurs.

throwing a "Floating Point Exception" and crashing when reprojecting Geodetic (epsg:4326) to Mercator (epsg:3857). I'm using an older version of GDAL in my application (3.4.1) but this problem still happens in GDAL 3.8.5 with proj 9.4.0 as I've shown in the Steps to Reproduce ...
