Identify values with a negative sign

is_signed() inspects the stored sign bit rather than comparing with zero. It therefore identifies negative zero as signed.

Usage

is_signed(x)

Arguments

x

A decimal-compatible vector.

Value

A logical vector with the same length as x.

Examples

is_signed(decimal(c("-2", "2", "-0", "0")))
#> [1]  TRUE FALSE  TRUE FALSE
