Comparisons with absolute epsilons are usually useful when comparing numbers to zero, for non-zero numbers it's advised to switch to relative epsilons instead to obtain meaningful results (check [1] for more details). The new API introduces approxEqAbs and approxEqRel, where the former aliases and deprecated the old `approxEq`, allowing the user to pick the right tool for the job. The documentation is meant to guide the user in the choice of the correct alternative. [1] https://randomascii.wordpress.com/2012/02/25/comparing-floating-point-numbers-2012-edition/ |
