largerEq(): Greater Than or Equal To
largerEq() tests whether the first value is greater than or equal to the second. It is appropriate for inclusive limits such as minimum balances, acceptable scores, and nonnegative constraints.
Writing clear boundaries
largerEq(10, 10) is true, unlike larger(). Combine it with smallerEq() and and() for a closed range. Use equal() when only exact equality matters.
Measurements and computed decimals can sit near a boundary because of floating-point precision. Compare a tolerance-adjusted value rather than relying on a rounded display, and ensure both sides use compatible units with to().
