## Convert numbers to ratio character vectors (two to one, one in three, five out of ten)

### Description

Convert numbers to ratio character vectors (two to one, one in three, five out of ten)

### Usage

ratio(x, sep = "in", max_n = Inf, negative = "negative", ...)

nom_ratio(x, sep = "in", max_n = Inf, negative = "negative", ...)

### Arguments

 x A numeric vector sep A character vector separating components of the ratio. Defaults to "in". 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 denomIf denom is not NULL, all fractions will have a denominator of denom. This will ignore all other arguments that affect the denominator. base_10If TRUE, all denominators will be a power of 10. common_denomIf TRUE, all fractions will have the same denominator. If the least common denominator is greater than max_denom, max_denom is used. max_denomAll 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.

### Details

x is converted to a fraction by fracture::frac_mat().

### Value

A character vector of the same length as x

Other number names: adverbial(), cardinal(), collective(), denominator(), numerator(), ordinal()

### Examples

paste0("Our team is outnumbered ", nom_ratio(10), ".")
paste0("The chances of winning are ", nom_ratio(1/1000000, sep = "in"), ".")

nom_ratio(c(1, 10, 100))
nom_ratio(c(0, 0.5, 1.5))
nom_ratio(c(0, 0.125, 0.625, 1), sep = "out of", common_denom = TRUE)
nom_ratio(5 / 10, sep = "in", base_10 = TRUE)
nom_ratio(6 / 25, sep = "in")
nom_ratio(6 / 25, sep = "out of", max_denom = 10)
