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

-

Node.js का उपयोग कर, मैं अभिव्यक्ति का मूल्यांकन कर रहा हूं: 

  0 & lt; संख्या। MIN_VALUE

मेरे आश्चर्य करने के लिए, यह सत्य देता है। ऐसा क्यों है? और: मैं सबसे छोटी संख्या कैसे प्राप्त कर सकता हूं जिसके लिए अपेक्षा अपेक्षा के अनुरूप काम करती है?

संख्या। MIN_VALUE है 5e-324 , अर्थात् न्यूनतम सकारात्मक संख्या जो कि फ्लोट परिशुद्धता के भीतर प्रदर्शित की जा सकती है, अर्थात यह जितना करीब हो सकता है जितना आप शून्य पर प्राप्त कर सकते हैं। यह परिभाषित करता है कि सबसे अच्छा रिज़ॉल्यूशन आपको देता है।

अब सबसे छोटा मूल्य संख्या.NEGATIVE_INFINITY है, हालांकि यह सख्त अर्थों में वास्तव में संख्यात्मक नहीं है।

javascript - data.match(var) not working it seems -

OK, I have this small block code, which is to scanned a number on the website, but for some reason There is a hip that it is not scanning at all. var regenges = / \ & lt; Span class = "currency-robux" data-to-"item-private-value-price" & gt; ([\ D,]) \ & LT; \ / Span \ & gt; /; Var ValueCiling = Data. Match (reggae); Value-song = number (value slicing location (",", "")); Is there anything wrong with that? This is related to the if statement if (value sling and lieutenant; = price watching) { < P> A function calls to move from there, but for some reason it does not seem to run at all. So I think the Regex is wrong but I'm not sure how. (There is a variable in PriceWinking , this is a snippet from the code.) On the website, I'm trying to remove it. & lt; Span class = "robux" data-plus = "item-privatesale-price" & gt; 115 & lt; / Span & gt; Keep in mind
