cardinal {nombre}

Convert numbers to cardinal character vectors (one, two, three)

Description

Convert numbers to cardinal character vectors (one, two, three)

Usage

cardinal(x, max_n = Inf, negative = "negative", ...)

nom_card(x, max_n = Inf, negative = "negative", ...)

Arguments

x

A numeric vector

max_n

A numeric vector. When the absolute value of x is greater than max_n, x remains numeric instead of being converted to words. If max_n is negative, no xs will be converted to words. (This can be useful when max_n is passed by another function.) Defaults to Inf, which converts all xs to words.

negative

A character vector to append to negative numbers. Defaults to "negative".

...

Arguments passed on to fracture::frac_mat

denom

If denom is not NULL, all fractions will have a denominator of denom. This will ignore all other arguments that affect the denominator.

base_10

If TRUE, all denominators will be a power of 10.

common_denom

If TRUE, all fractions will have the same denominator.

If the least common denominator is greater than max_denom, max_denom is used.

max_denom

All denominators will be less than or equal to max_denom.

If base_10 is TRUE, the maximum denominator will be the largest power of 10 less than max_denom.

A max_denom greater than the inverse square root of machine double epsilon will produce a warning because floating point rounding errors can occur when denominators grow too large.

Value

A character vector of the same length as x

Fractions

Decimal components of x are automatically converted to fractions by fracture::frac_mat().
