decimal-point

I am trying to find the square root of 2 to 100 decimal places, but it only shows to like 10 by default, how can I change this? decimal module comes in handy. >>> from decimal import * >>> getcontext().prec = 100 >>> Decimal(2).sqrt() Decimal('1.414213562373095048801688724209698078569671875376948073176679737990732478462107038850387534327641573') You can use the decimal module for arbitrary precision numbers: import decimal d2 = decimal.Decimal(2) # Add a context with an arbitrary precision of 100 dot100 = decimal.Context(prec=100) print d2.sqrt(dot100) If you need the same kind of ability

public void LoadAveragePingTime() { try { PingReply pingReply = pingClass.Send("logon.chronic-domination.com"); double AveragePing = (pingReply.RoundtripTime / 1.75); label4.Text = (AveragePing.ToString() + "ms"); } catch (Exception) { label4.Text = "Server is currently offline."; } } Currently my label4.Text get's something like: "187.371698712637". I need it to show something like: "187.37" Only two posts after the DOT. Can someone help me out? string.Format is your friend. String.Format("{0:0.00}", 123.4567); // "123.46" Anas If you want to take just two numbers after comma you can use the

This is what I have right now: $("#number").val(parseFloat($("#number").val()).toFixed(2)); It looks messy to me. I don't think I'm chaining the functions correctly. Do I have to call it for each textbox, or can I create a separate function? If you're doing this to several fields, or doing it quite often, then perhaps a plugin is the answer. Here's the beginnings of a jQuery plugin that formats the value of a field to two decimal places. It is triggered by the onchange event of the field. You may want something different. <script type="text/javascript"> // mini jQuery plugin that formats to

This question already has an answer here: Difference between parseInt and valueOf in java? 12 answers Aside from Integer.parseInt() handling the minus sign (as documented), are there any other differences between Integer.valueOf() and Integer.parseInt() ? And since neither can parse , as a decimal thousands separator (produces NumberFormatException ), is there an already available Java method to do that? corsiKa Actually, valueOf uses parseInt internally. The difference is parseInt returns an int primitive while valueOf returns an Integer object. Consider from the Integer.class source: public

Is it possible to change the decimal comma from "." (dot) to other character (comma) in MySQL output? I don't want to use functions like FORMAT , I just want to use all the queries I normaly use without any modification. I'm looking for some setting (of some variable, locale etc.). I tried to search the manual but without success. ypercubeᵀᴹ No, you can't. That's the SQL standard and MySQL complies with it (in that point at least). The problem is not really with output (as you mention, there are various FORMAT functions in most DBMSs) but with INSERT . If you could use comma , for example as
