node.js - Why is 0 less than Number.MIN_VALUE in JavaScript?

Asked 10 years, 9 months ago

Viewed 18k times

Using Node.js, I'm evaluating the expression:

0 < Number.MIN_VALUE

To my surprise, this returns true. Why is that? And: How can I get the smallest number available for which the comparison works as expected?

Number.MIN_VALUE is 5e-324, i.e. the smallest positive number that can be represented within float precision, i.e. that's as close as you can get to zero. It defines the best resolution floats give you.

Now the overall smallest value is Number.NEGATIVE_INFINITY although that's not really numeric in the strict sense.

Number.MIN_VALUE is equivalent to 5e-324 , which is greater than 0.

Since Number.MIN_VALUE = 5e-324 = 5 x 10^-324 and it's greater than 0(a little bit greater).

`Number.MIN_VALUE` is equal to 5e-324 or 5*(10^-324);

it's math. any positive number is greater than zero.

Use -Number.MAX_VALUE instead of Number.MIN_VALUE to compare:

0 > -Number.MAX_VALUE returns true.
