Java double comparison epsilon

double comparison epsilon I wrote a class that tests for equality less than and greater.. accuracy of a half cent. 59.005 compared to 59.395. Is the epsilon I chose adequate for those cases private final static double.. the two doubles has a difference less then a given double epsilon . Determining the given epsilon is highly dependant on the precision..

be really careful you can test whether it is within some epsilon of zero with something like double epsilon 0.0000001 if f 0.. is within some epsilon of zero with something like double epsilon 0.0000001 if f 0 epsilon .. else if f 0 epsilon .. else f equals.. zero with something like double epsilon 0.0000001 if f 0 epsilon .. else if f 0 epsilon .. else f equals zero Or you can simply..
