near function

Compare two numeric vectors

This is a safe way of comparing if two vectors of floating point numbers are (pairwise) equal. This is safer than using ==, because it has a built in tolerance

near(x, y, tol = .Machine$double.eps^0.5)

Arguments

• x, y: Numeric vectors to compare
• tol: Tolerance of comparison.

Examples

sqrt(2) ^ 2 == 2
near(sqrt(2) ^ 2, 2)
