# format.integer64: Unary operators and functions for integer64 vectors In bit64: A S3 Class for Vectors of 64bit Integers

## Description

Unary operators and functions for integer64 vectors.

## Usage

 ``` 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 36``` ```## S3 method for class 'integer64' format(x, justify="right", ...) ## S3 method for class 'integer64' is.na(x) ## S3 method for class 'integer64' is.nan(x) ## S3 method for class 'integer64' is.finite(x) ## S3 method for class 'integer64' is.infinite(x) ## S3 method for class 'integer64' !x ## S3 method for class 'integer64' sign(x) ## S3 method for class 'integer64' abs(x) ## S3 method for class 'integer64' sqrt(x) ## S3 method for class 'integer64' log(x, base) ## S3 method for class 'integer64' log2(x) ## S3 method for class 'integer64' log10(x) ## S3 method for class 'integer64' floor(x) ## S3 method for class 'integer64' ceiling(x) ## S3 method for class 'integer64' trunc(x, ...) ## S3 method for class 'integer64' round(x, digits=0) ## S3 method for class 'integer64' signif(x, digits=6) ## S3 method for class 'integer64' scale(x, center = TRUE, scale = TRUE) ```

## Arguments

 `x` an atomic vector of class 'integer64' `base` an atomic scalar (we save 50% log-calls by not allowing a vector base) `digits` integer indicating the number of decimal places (round) or significant digits (signif) to be used. Negative values are allowed (see `round`) `justify` should it be right-justified (the default), left-justified, centred or left alone. `center` see `scale` `scale` see `scale` `...` further arguments to the `NextMethod`

## Value

`format` returns a character vector
`is.na` and `!` return a logical vector
`sqrt`, `log`, `log2` and `log10` return a double vector
`sign`, `abs`, `floor`, `ceiling`, `trunc` and `round` return a vector of class 'integer64'
`signif` is not implemented
