22 ## @code{bitmax} is deprecated and will be removed in Octave version 4.6. |
| 20696 | 23 ## Use @code{flintmax (precision) - 1} for the equivalent functionality. |
| 24 ## | |
| 25 ## Return the largest integer @var{r} that can be represented within a | |
| 26 ## floating point value. | |
| 27 ## | |
| 28 ## The default class is @qcode{"double"}, but @qcode{"single"} is a valid | |
| 29 ## option. On IEEE 754 compatible systems, @code{bitmax} is | |
| 30 ## @w{@math{2^{53} - 1}} for @qcode{"double"} and @w{@math{2^{24} - 1}} for | |
| 31 ## @qcode{"single"}. | |
| 32 ## | |
| 33 ## @seealso{flintmax, intmax, realmax, realmin} | |
| 34 ## @end deftypefn | |
| 35 | |
| 36 ## Deprecated in version 4.2 | |
