moreOrLessEquals function
Asserts that two doubles are equal, within some tolerated error.
Two values are considered equal if the difference between them is within
precisionErrorTolerance of the larger one. This is an arbitrary value
which can be adjusted using the epsilon argument. This matcher is intended
to compare floating point numbers that are the result of different sequences
of operations, such that they may have accumulated slightly different
errors.
See also:
- closeTo, which is identical except that the epsilon argument is required and not named.
- inInclusiveRange, which matches if the argument is in a specified range.
- rectMoreOrLessEquals and offsetMoreOrLessEquals, which do something similar but for Rects and Offsets respectively.
Implementation
Matcher moreOrLessEquals(double value, { double epsilon = precisionErrorTolerance }) {
return _MoreOrLessEquals(value, epsilon);
}
