is_equal: Check Numeric Equality within a Tolerance

Description

Compares two numeric vectors element-wise using an adaptive tolerance sequence ranging from 10^-19 to 10^tol_max. The smallest tolerance at which the values are considered equal is returned as the corresponding name in the output.

Usage

is_equal(x, y, tol_max = -1)

Value

A logical vector indicating whether each element pair is equal within the detected tolerance. The names reflect the tolerance used.

Arguments

x

(numeric)
first vector to compare.

y

(numeric)
second vector to compare.

tol_max

(integerish(1))
the maximum tolerance exponent (as a power of 10).

is_equal(c(3, 4), c(3.01, 4.11), tol_max = 0)
