num2char: Numeric to character string

In raredd/rawr: rawr miscellaneous

Numeric to character string

Description

Convert a number to its word equivalent.

Usage

num2char(x, informal = FALSE, cap = TRUE)

Arguments

x	an integer to convert to words; can be negative or positive but decimals will be rounded first
informal	logical; if TRUE, adds "and" before tens or ones
cap	logical; if TRUE, capitalizes the first word

Details

Whole numbers twenty-one through ninety-nine are hyphenated when they are written out whether used alone or as part of a larger number; for example: "twenty-one" or "one million twenty-one."

Whole numbers in this range are not hyphenated for other orders of magnitude; for example, 52,052 is written "fifty two thousand fifty- two" and not "fifty-two thousand fifty-two." This rule applies only to two-word numbers 21-99.

Informal and formal case differ only by the use of "and" to separate 1-99: "one hundred one" is the formal case, and "one hundred and one" is the informal case.
