I am trying to write a simple C program that takes the input from user in metres and prints the output in kilometres, yards and miles rounded to 4 decimal places. I have used this 1 meter = 0.001 kilometers = 1.094 yards = 0.0006215 miles When I write this, I get the output as intended: #include &lt;stdio.h&gt; int main() {    int m;    float km, y, mi;    scanf(&quot;%d&quot;,&amp;m);    km=(m*0.001);    y=(m*1.094);    mi=(m*0.0006215);    printf(&quot;%.4f\n%.4f\n%.4f&quot;,km,y,mi);    return 0; }  Output: 0.1000 109.4000 0.0622 But, when I write this I get the third output wrong: #include &lt;stdio.h&gt; int main() {    int m;    scanf(&quot;%d&quot;,&amp;m);    printf(&quot;%.4f\n%.4f\n%.4f&quot;,(m*0.001),(m*1.094),(m*0.0006215));    return 0; }  Output: 0.1000 109.4000 0.0621 Can you please help me find the reason for this difference?  Edit-1 here I gave input 100. float y=100*0.0006215; printf(&quot;%f&quot;,y);  gave output 0.062150 and this printf(&quot;%f&quot;,100*0.0006215);  also gave output 0.062150  Edit-2 float y=100*0.0006215; printf(&quot;%.4f&quot;,y);  gave output 0.0622 while: printf(&quot;%.4f&quot;,100*0.0006215);  gave output 0.0621 whereas in Edit-1 both displayed the same output.
Consider the following code:   0.1 + 0.2 == 0.3  -&gt;  false   0.1 + 0.2         -&gt;  0.30000000000000004   Why do these inaccuracies happen?
Is it a bad practice to catch Throwable? "work for" / "work in" / "work at" I would like to know what usually follows after each proposition in sentences with the word &quot;work&quot;. These are what I understand so far: I work for my boss. ( usually for certain person ) I work in a accounting corporation. (usually for business area ) I work at Samsung. ( usually for specific name of company ) Could you please tell me if I understand rightly? sum of double precision gives weird results Setting a fill and border is pretty easy in apps like Illustrator and Gravit Designer but in Blender. I've found it to be more tedious as I can't find anything online to solve this problem.  The picture above is a simple 2d mouth with lips. I would like to be able to move the lips and still have a fill but in Blender I needed to add another path for the mouth. Is there anyway I can move my lips path while having it also take the exact same shape (but not material) as my mouth's path?

I heard that while dribbling the ball, if the ball rises above shoulder level then it is a turnover. I don't have any idea about this rule. I just saw now that a new build had rolled out in which the comment upvote and flag options are always visible. Previously, one had to mouse over the area in order to see them.  Why was this just changed? Is it to support touch screens? I'll admit, it was difficult to find the flag button using my touchscreen laptop running Microsoft Edge.

How can I achieve either? NS list does not match list from parent zone I'm attempting to figure out an error message that I got from dnsstuff.com when examining my DNS records.  The error reads as follows.     NS list does not match list from parent zone. This should be addressed because queries for this domain may require an extra lookup (and more overhead) because there is no direct relationship between the NS records at the parent and the NS records at the authoritative servers. This can cause delays. The mismatched NS list is:      nameserver ns1.domain.co. | xxx.xx.xxx.xxx is missing NS2.domain.co. | yy.yyy.yy.yyy   There are a couple questions I have regarding this.   What is the difference between a parent and authoritative zone?  In other forum posts I've seen, the seem to be used interchangeably (although that could be my misperception). What does it mean for the NS list not to match the list from the parent zone?  What is "the list from the parent zone" to which they refer? How might you recommend that I resolve this?

I've tried Travelex in Heathrow, a currency exchange place, and the post office.  The currencies include cash from: Mongolia, Kyrgyzstan, Kazakhstan and Uzbekistan.  Most of the responses when shown the money is to the tone of "What the hell currency is this?" which doesn't fill me with confidence.  Any suggestions welcomed for places that may change this.

How to apply for a UK standard visitor visa as a family? Can I use Named Credential merge fields as URL parameters on the endpoint? I have a named credential as follows:  Name   Test_Credential URL    https://www.somesite.com Identity Type    Named Principal Authentication Protocol    Password Authentication Username   foobar Password   mySomeSiteDeveloperKey Generate Authorization Header   FALSE Allow Merge Fields in HTTP Header    TRUE Allow Merge Fields in HTTP Body     TRUE   The service that I am trying to authenticate against uses URL parameters to pass in the developer key and username. Is there any way to use  to pass those in to the URL?   The Named Credential attributes seem not to get decoded until the request is actually sent, as debugging the endpoint, or headers if I set them per the linked doc, show the un-merged data. I can get the callout to go to the right place, and return the expected error because the auth information is not provided. Anybody know of a "show me my HTTP request" site that I could point to to get a better idea of how this works?  I've tried both of these:  req.setEndpoint('callout:Test_Credential/api/action?id={!$Credential.Password}&amp;account={!$Credential.UserName}');  req.setEndpoint('callout:Test_Credential/api/action' + '?id=' + '{!$Credential.Password}' + '&amp;account=' + '{!$Credential.UserName}');   (Edited to remove the part about $Credential vs. $Test_Credential as I was able to determine that it is the former, and see the merged creds by calling out to .) The question asks it all really. When referring to a master's degree, do you use an apostrophe or not? That is, is it "a master's" or "a masters"?
