  2. Type signature - Wikipedia

    en.wikipedia.org/wiki/Type_signature

    In the Java virtual machine, internal type signatures are used to identify methods and classes at the level of the virtual machine code. Example: The method String String. substring (int, int) is represented in bytecode as Ljava / lang / String. substring (II) Ljava / lang / String;. The signature of the main method looks like this: [2]

  3. printf (Unix) - Wikipedia

    en.wikipedia.org/wiki/Printf_(Unix)

    In Unix and Unix-like operating systems, printf is a shell builtin (and utility program [2]) that formats and outputs text like the same-named C function. Originally named for outputting to a printer, it actually outputs to standard output. [3] The command accepts a format string, which specifies how to format values, and a list of values.

  4. printf - Wikipedia

    en.wikipedia.org/wiki/Printf

    printf is a C standard library function that formats text and writes it to standard output. The name, printf is short for print formatted where print refers to output to a printer although the functions are not limited to printer output. The standard library provides many other similar functions that form a family of printf-like functions.

    1 Control-C has typically been used as a "break" or "interrupt" key. 2 Control-D has been used to signal "end of file" for text typed in at the terminal on Unix / Linux systems. Windows, MsDOS, and older minicomputers used Control-Z for this purpose.

    Being approximately 1.695 × 10 694127911065419641, this number is far too large for any currently known primality test. It has no prime factor below 1 × 10 36. [2] There are probably no other double Mersenne primes than the four known. [1] [3] Smallest prime factor of (where p is the nth prime) are

  7. Logarithmically concave function - Wikipedia

    en.wikipedia.org/wiki/Logarithmically_concave...

    [1] Every concave function that is nonnegative on its domain is log-concave. However, the reverse does not necessarily hold. An example is the Gaussian function f(x) = exp(−x 2 /2) which is log-concave since log f(x) = −x 2 /2 is a concave function of x. But f is not concave since the second derivative is positive for | x | > 1:

    2033 DOUBLE PRIME = seconds, inches The difference is that ' and " are vertical, while ′ and ″ are slanted slightly (which is how I've always seen inches and feet anyway). --Elektron 09:27, 2004 Jun 14 (UTC) I removed the statement that a single prime is used to denote minutes of time and the double prime to denote seconds of time.
