Test whether elements in vector x are effectively zero, within the square root of machine tolerance for a floating point number.
almostZero(x, y = 0, tolerance = sqrt(.Machine$double.eps))
| x | Numeric vector of values to compared against 0 |
|---|---|
| y | Value to be compared against. Default is 0. |
| tolerance | The maximum difference between x and y necessary to call a value non-zero |
TRUE or FALSE for each element of the vector x.
Returns TRUE for all vector elements that are within rounding error of zero.
