is_equal: Check Numeric Equality within a Tolerance

In stratallo: Optimum Sample Allocation in Stratified Sampling

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)

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).

Value

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