A common scenario is to simply run <i>klee-stats</i> on <i>klee-last</i>. + + <p> + In order to limit printed information only to the values of measured times, + the following options can be used: + + <ul> + <li><i>--print-rel-times</i>—display time values relative + to measured execution time</li> + + <li><i>--print-abs-times</i>—display absolute time values</li> + </ul> + + The <i>--precision</i> option can be used to configure the number of fractional + digits displayed in floating point values. By default, 2 fractional digits + are displayed, but in some cases that might be not sufficient—if the value + is very small, e.g. 0.0001, with 2-digits precision it will be printed as 0.00. + </p> + + <p> Various other options can be used to specify what values are + displayed and how they are displayed. Options for comparison of + statistics are also provided.
