Compute the adjusted exponent

adjusted() returns the position of the most significant digit after accounting for the stored exponent. For a finite nonzero value, this is equivalent to the base-10 order of magnitude. The representation of zero retains its exponent, so differently scaled zeros can have different adjusted exponents.

Usage

adjusted(x)

Arguments

x

A decimal-compatible vector.

Value

An integer vector with the same length as x. Infinities, NaNs, and R missing values produce NA_integer_.

Examples

adjusted(decimal(c("123", "0.01")))
#> [1]  2 -2
