Methods for comparison (greater than, etc) in package Brobdingnag

Note

As for min() and max(), comparison is not entirely straightforward in the presence of NAs.

The low-level workhorses are .Brob.equal() for equality and .Brob.greater() for ‘strictly greater than’. All other comparisons are calculated by combining these two.

Comparison [function .Brob.compare()] explicitly tests for a zero length argument and if given one returns logical(0) to match base behaviour.

Examples

  a <- as.brob(10)^(0.5 + 97:103)
  a < 1e100
#> [1]  TRUE  TRUE  TRUE FALSE FALSE FALSE FALSE
