fjpanag opened a new issue, #6945:
URL: https://github.com/apache/incubator-nuttx/issues/6945

   `strtod()` can produce wrong results in some cases of invalid input.
   
   Take a look at the following snippet:
   
   ```c
       char * str = "1e";
       char * end;
       
       int ret = strtod(str, end);
       
       printf("%d\n", ret);
   
   ```
   
   On my Linux machine, this prints `0`, while on NuttX it prints `1`.
   
   It seems that when the exponent is not correctly parsed, it is assumed to be 0 instead of returning an error.
