An interrupt generated by the 387 (or conceptual 387, if you have a
486DX or above). It is triggered whenever some event occurs for which
the 387's control word says to generate one. With DJGPP, that typically
includes use of NaN or Inf, and all the math operations that cause them
(division by 0, sqrt(negative), log(negative), etc.) In DJGPP, integer
division by 0 also causes SIGFPE.
For more info, see an Intel manual, or some other source.
