You can use the decimal formatter for this as- NumberFormat formatter = new DecimalFormat("#0.00"); Log.d("formatted no is ",""+formatter.format(4.0)); Edit You can modify your code like this- public void onButtonClick(View v) after some formulas velocity2 = velocity * 0.00508; drop2 = pressuredrop * 249.174; vel.setText(formatter.format(velocity2)); dr.setText(formatter.format(drop2)); } ...

Convert to integer? static int GetDigit(int number, int k) { // k is the positiong of the digit I want to get from the number // I want to divide integer number to 10....0 (number of 0s is k) and then % 10 // to get the last digit of...

We can write the numbers you are looking for like this: re_n = (?:[^x]|^)\d\d\d(?:[^ip]|$) Then the whole expression is: ^(?!.*re_n.*re_n.*$).*(re_n) which basically eliminates double numbers using a negative lookahead following the line start anchor, then matches a valid number. The interpolated expression looks ugly: /^(?!.*(?:(?:[^x]|^)\d\d\d(?:[^ip]|$)).*(?:(?:[^x]|^)\d\d\d(?:[^ip]|$)).*$).*((?:(?:[^x]|^)\d\d\d(?:[^ip]|$)))/ This Perl code: my $re_n...

Use a regex with a capture group: .*?S.*?(\d{2}).*?E.* > "some.text.S**01**E02.partofstring.mkv" -replace '.*?S.*?(\d{2}).*?E.*','$1' 01 > "some.textstring.S**01**E02.partofstring.mkv" -replace '.*?S.*?(\d{2}).*?E.*','$1' 01 ...

Your stopping condition is wrong: q%10!=0 will become "true" as soon as you reach the first zero in a decimal representation. For example, for a number 6540321 your program would add 32+22+12, and stop, because the next digit happens to be zero. Squares of 6, 5, and 4 would never...

Apply the same zfill function in a list comprehension, like this >>> [str(item).zfill(6) for item in data] ['000001', '000010', '000313', '004000', '051234', '123456'] Alternatively, you can use the string's format method, with format specifiers, like this >>> ["{:06d}".format(item) for item in data] ['000001', '000010', '000313', '004000', '051234', '123456'] If you...

This should do the trick: def format(d: Double) = BigDecimal(d).scale match { case x if x > 2 => "%.3f".format(d) case _ => d.toInt.toString } ...

You can extract the numbers: String numberStr = yourStr.replaceAll("[^0-9]", ""); if you want to keep decimal point use: yourStr.replaceAll("[^\\.0123456789]",""); then you can check for individual numbers. To add space between numbers: String numberStr = yourStr.replaceAll("[^0-9]", " "); To get only the numbers, and store them to a string array: String...

Read the number, use an array of size 10 to count the occurrences, loop over the cyphers: int n; std::cin >> n; int occ[10] = { 0 }; while (n > 0) { const int c = n % 10; occ[c]++; n /= 10; } at the end, if occ[i]...

There are probably better solutions, but this one is slightly shorter: int theNumber = 204398234; int theDigitPlace = 3;//hundreds place int theDigit = (theNumber/(int)(pow(10, theDigitPlace - 1))) % 10; In your case, it divides the number by 100 to get 2043982 and then "extracts" the last decimal digit with the...

From this std::numeric_limits::digits reference: The value of std::numeric_limits::digits is the number of digits in base-radix that can be represented by the type T without change. For integer types, this is the number of bits not counting the sign bit. And later it states that for char the result is CHAR_BIT...

Do both at the same time There is no need for a second check. Regex allows you to check both that the folder names contains natives, and that natives is followed by a dash and 14 digits, in a single pass. Use this regex: natives-\d{14} Or, if the 14 digits...

You're missing quotes around the string. In C, a string is actually specified by a sequence of string literals. So you can do: #define DIGITS "10" printf( "%0" DIGITS "d\n", myvalue ); The preprocessor can also generate strings from other tokens (such as numbers). Check into the stringize operator (#),...

It seems like your toolchain has a 32-bit int type. The maximum value representable in such a type is 231-1, or 2,147,483,647. As you can see, that's a 10-digit number. You'll need to use a different type that supports larger numbers if you want to use this kind of an...

Your while condition is Math.Abs(n) > 1, but in the case of 10, you are only greater than 1 the first time. You could change this check to be >=1 and that should fix your problem. do { n = n / 10; i++; } while(Math.Abs(n) >= 1); ...
