Fix isnan() checks to declare main() returning 'int' and use floating argument to isnan() avoiding recent (gcc 5) compiler noise. Since last update: ../../.. version 5.5.2.1 - fixed a small error in new and improved MIP_stepOF function to find integer solutions. ../../.. version 5.5.2.2 - For integer models with semi-cont variables it happened sometimes that a message "fillbranches_BB: Inconsistent equal-valued bounds for ..." occured and that the semi-cont condition was not respected. - New functions added: get_accuracy to get the numeric accuracy after solve. - New functions added: set_break_numeric_accuracy, get_break_numeric_accuracy to let lp_solve return ACCURACYERROR instead of FEASIBLE when numerical accuracy if worse then the provided values. In the past, lp_solve only returned a non-optimal status in case of very severe numerical instability. Now it will return already ACCURACYERROR when it finds a relative inaccuracy of 5e-7 - When reading a model from the lp-format and important issues are detected such as already bounds on variables being overruled later with for example a bin keyword, this is now reported in the default verbose level such that this is seen easier. 08/05/16 version 5.5.2.3 - For some models with integer variables, lp_solve did not find the most optimal solution.
