format.integer64: Unary operators and functions for integer64 vectors

Description

Unary operators and functions for integer64 vectors.

Usage

format(x, justify="right", ...)
# S3 method for integer64
is.na(x)
# S3 method for integer64
is.nan(x)
# S3 method for integer64
is.finite(x)
# S3 method for integer64
is.infinite(x)
# S3 method for integer64
!(x)
# S3 method for integer64
sign(x)
# S3 method for integer64
abs(x)
# S3 method for integer64
sqrt(x)
# S3 method for integer64
log(x, base)
# S3 method for integer64
log2(x)
# S3 method for integer64
log10(x)
# S3 method for integer64
floor(x)
# S3 method for integer64
ceiling(x)
# S3 method for integer64
trunc(x, ...)
# S3 method for integer64
round(x, digits=0)
# S3 method for integer64
signif(x, digits=6)
# S3 method for integer64
scale(x, center = TRUE, scale = TRUE)

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

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

Examples

Run this code

  sqrt(as.integer64(1:12))
# \dontshow{
i <- -999:999
for (s in -3:3){
r <- as.integer64(round(as.integer(i), s))
  r64 <- round(as.integer64(i), s)
  stopifnot(identical(r,r64))
}
# }
