Identify subnormal decimal values

is_subnormal() reports whether each finite, nonzero value is subnormal under the active decimal context. A value can therefore be subnormal in one context and normal in another.

Usage

is_subnormal(x)

Arguments

x

A decimal-compatible vector.

Value

A logical vector with the same length as x.

Examples

x <- decimal("0.001")
with_decimal_context(
  decimal_context(precision = 3L, emin = -2L),
  is_subnormal(x)
)
#> [1] TRUE
