Cast to deb_decimal

Cast x to a deb_decimal vector.

Usage

deb_as_decimal(x, ...)

# S3 method for default
deb_as_decimal(x, ...)

# S3 method for deb_decimal
deb_as_decimal(x, ...)

# S3 method for deb_lsd
deb_as_decimal(x, unit = c("l", "s", "d"), ...)

# S3 method for deb_tetra
deb_as_decimal(x, unit = c("l", "s", "d", "f"), ...)

# S3 method for numeric
deb_as_decimal(x, unit = c("l", "s", "d", "f"), bases = c(20, 12), ...)

# S3 method for logical
deb_as_decimal(x, unit = c("l", "s", "d", "f"), bases = c(20, 12), ...)

# S3 method for list
deb_as_decimal(x, unit = c("l", "s", "d", "f"), bases = c(20, 12), ...)

Arguments

x

An object to coerce to deb_decimal.

...

Arguments passed on to further methods.

unit

A character vector of length one indicating the unit for the decimalized values, either "l" (libra, the default), "s" (solidus), or "d" (denarius).

bases

Numeric vector of length 2 used to specify the bases for the solidus or s and denarius or d units. Default is c(20, 12), which conforms to the most widely used system of 1 pound = 20 shillings and 1 shilling = 12 pence.

Value

A deb_decimal vector.

Details

Like deb_as_lsd(), deb_as_decimal() provides a method to cast a list of numeric vectors of length 3 to deb_decimal. This may be helpful because the data is input by the value instead of by the unit.

Examples

# Cast a deb_lsd vector to deb_decimal
x <- deb_lsd(l = c(5, 3, 7),
             s = c(16, 5, 6),
             d = c(6, 0, 8))
deb_as_decimal(x)

#> [1] 5.825000 3.250000 7.333333
#> # Unit: libra
#> # Bases: 20s 12d

# Bases are automatically applied when
# casting from deb_lsd to deb_decimal
x2 <- deb_lsd(l = c(5, 3, 7),
              s = c(16, 5, 6),
              d = c(6, 0, 8),
              bases = c(60, 16))
deb_as_decimal(x2)

# Cast a deb_tetra vector to deb_decimal
# Bases are automatically applied, creating
# a deb_decimal vector with three bases units.
y <- deb_tetra(l = c(5, 13, 7),
               s = c(12, 8, 16),
               d = c(3, 11, 0),
               f = c(1, 3, 2))
deb_as_decimal(y)

# Cast a numeric vector to deb_decimal
z <- c(5.825, 3.25, 22/3)
deb_as_decimal(z)

#> [1] 5.825000 3.250000 7.333333

# Use the unit and bases arguments to specify
# the unit and apply non-default bases
deb_as_decimal(z, unit = "s", bases = c(60, 16))

# Casting a list to deb_decimal provides an
# alternative to get lsd values to deb_decimal.
lsd_list <- list(c(5, 12, 3),
                 c(13, 8, 11),
                 c(7, 16, 0))
deb_as_decimal(lsd_list)

#> [1]  5.61250 13.44583  7.80000
