c++ - How Can I Round Type Float Variable WHEN PRINTED In C Language? -

-

संभव डुप्लिकेट:

इससे पहले कि मैं किसी भ्रम का कारण बनूं ... यह वह है जो मैं सी ++ में उपयोग कर रहा हूं 

  cout.setf (ios :: fixed); .. cout.precision (3); ..   
 मैंने इसे सभी प्रिंट किए गए नंबरों को सी + + में 3 दशमलव स्थानों पर गोल करने के लिए प्रयोग किया था। मैं सी में काम करने के लिए नहीं मिल सकता। कोई मदद?   
 
 
 इसे करें:  
  printf ("% 0.3f", myFloat);

mysql - BLOB/TEXT column 'value' used in key specification without a key length -

-
I have developed an extension which works up to 1.6 on Magren (I'm trying Enterprise Edition, And I think the community is the same problem, because it is the same code). In my install script, I see the $ installer-> gt; CreateEntityTables ($ this- & gt; getTable ('alphanum / info')); The installation is done until it is not in the _text unit table. It crashed there! It turns out that when I log in to SQL and run it via PHPmyadmin, then this error is: Blob / Text column 'value' is used without the key 'key' .

I am an experienced TCL developer and write my own processes to help myself. I call it a proc i callVar, print out the value of the variable in a certain format, so I know that it is variable and what is the value "set foo 1; putVar foo" result 'foo = "1" I want to do the same thing in Python, but I can not find the answer :( In TCL I use the up command because when I pass the name of the variable, then I can see the value at the top. . I understand that an advanced light in the dragon There is no mechanism of r, but with its introspection capability, I would think that this is something trivial, but I am not getting the answer anywhere. It seems that this should work: and expanded: def foo (): y = "Hello World" printwor ("y") foo () y = "Hello World " You can, but you should not do so if your code is correct If is needed , then there is something wrong with your design, and you should probably use the dictionar...
