+description: >
+  Number.MIN_VALUE is approximately 5e-324. We can't directly compare it as the spec states:
+
+  In the IEEE 754-2019 double precision binary representation, the smallest possible value is a denormalized number.
+  If an implementation does not support denormalized values, the value of Number.MIN_VALUE must be the smallest
+  non-zero positive value that can actually be represented by the implementation.
