## Convert decimals to a matrix of numerators and denominators

### Description

Convert decimals to a matrix of numerators and denominators

### Usage

```frac_mat(
x,
...,
denom = NULL,
base_10 = FALSE,
common_denom = FALSE,
mixed = FALSE,
max_denom = 1e+07
)

as.frac_mat(x)

is.frac_mat(x)
```

### Arguments

 `x` A vector of decimals or, for `as.frac_mat()`, a character vector created by `fracture()` `...` These dots are for future extensions and must be empty. `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. `mixed` If `TRUE`, `integer` components will be displayed separately from fractional components for `x` values greater than 1. If `FALSE`, improper fractions will be used for `x` values greater than 1. `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 matrix with the same number of columns as the length of `x` and rows for `integer`s (if `mixed` is `TRUE`), `numerator`s, and `denominator`s.

`fracture()` to return a character vector of fractions.

### Examples

```x <- (6:1) / (1:6)

frac_mat(x)
frac_mat(x, common_denom = TRUE)

frac_mat(x, base_10 = TRUE)
frac_mat(x, base_10 = TRUE, max_denom = 100)
frac_mat(x, base_10 = TRUE, common_denom = TRUE)
frac_mat(x, base_10 = TRUE, common_denom = TRUE, max_denom = 100)

frac_mat(x, mixed = TRUE)
frac_mat(x, mixed = TRUE, common_denom = TRUE)
frac_mat(x, mixed = TRUE, base_10 = TRUE)
frac_mat(x, mixed = TRUE, base_10 = TRUE, max_denom = 100)
frac_mat(x, mixed = TRUE, base_10 = TRUE, common_denom = TRUE)
frac_mat(x, mixed = TRUE, base_10 = TRUE, common_denom = TRUE, max_denom = 100)
```
