IEEE Floating-Point Arithmetic (Fortran Programming Guide)

WebAs you want to do calculations with floating point numbers anyway, I suggest you change at least one of the numbers in each multiplication to float, i.e. 2891000*4450.0, thereby forcing the compiler to cast everything to real before doing the calculation. You probably also want to use double precision, but that’s not your problem here. http://www.nacad.ufrj.br/online/intel/Documentation/en_US/compiler_f/main_for/fpops/fortran/fpops_fpew_f.htm WebOverflow Underflow Loss of precision in converting into floating point Adding numbers of very different magnitudes Subtracting numbers of similar magnitudes Multiplying and dividing Overflow Overflow occurs when the number you are trying to express in floating point is too large in magnitude. hikvision contact support

WebWhen a serious runtime error is encountered or a deadly signal is emitted (segmentation fault, illegal instruction, bus error, floating-point exception, and the other POSIX signals that have the action ‘ core ’), the Fortran runtime library tries to output a backtrace of the error. -fno-backtrace disables the backtrace generation.
