Format Numbers Keeping Classes Distinguishable

Description

Format (generalized) numbers in a way that their classes are distinguishable. Contrary to format() which uses a common format for all elements of x, here, each entry is formatted individually.

Usage

formatN(x, ...)
## Default S3 method:
formatN(x, ...)
## S3 method for class 'integer'
formatN(x, ...)
## S3 method for class 'double'
formatN(x, ...)
## S3 method for class 'bigz'
formatN(x, ...)
## S3 method for class 'bigq'
formatN(x, ...)

Arguments

x	any R object, typically “number-like”.
...	potentially further arguments passed to methods.

Value

a character vector of the same length as x, each entry a representation of the corresponding entry in x.

Examples

## Note that each class is uniquely recognizable from its output:
formatN(    -2:5)# integer
formatN(0 + -2:5)# double precision
formatN(as.bigz(-2:5))
formatN(as.bigq(-2:5, 4))
