Classify decimal values

number_class() returns the General Decimal Arithmetic class of each value. Possible finite classes include "+Normal", "-Normal", "+Subnormal", "-Subnormal", "+Zero", and "-Zero"; infinities and NaNs have their corresponding class names. Normal and subnormal classes depend on the active decimal context.

Usage

number_class(x)

Arguments

x

A decimal-compatible vector.

Value

A character vector with the same length as x. R missing values produce NA_character_.

Examples

number_class(decimal(c("1", "-0", "Infinity", "NaN")))
#> [1] "+Normal"   "-Zero"     "+Infinity" "NaN"
