Equals Sign

The subject of equals sign encompasses a wide range of important elements. Why does a base64 encoded string have an = sign at the end. I know what base64 encoding is and how to calculate base64 encoding in C#, however I have seen several times that when I convert a string into base64, there is an = at the end. A few questions cam... bash - Shell equality operators (=, ==, -eq) - Stack Overflow. = and == are for string comparisons -eq is for numeric comparisons -eq is in the same family as -lt, -le, -gt, -ge, and -ne == is specific to bash (not present in sh (Bourne shell), ...).

Using POSIX = is preferred for compatibility. In bash the two are equivalent, and in sh = is the only one that will work. operators - What does ":=" do? In computer programming languages, the equals sign typically denotes either a boolean operator to test equality of values (e.g. as in Pascal or Eiffel), which is consistent with the symbol's usage in mathematics, or an assignment operator (e.g.

as in C-like languages). Comparing Java enum members: == or equals()? This perspective suggests that, i know that Java enums are compiled to classes with private constructors and a bunch of public static members. When comparing two members of a given enum, I've always used .equals(), e.g. notation - What does := mean?

- Mathematics Stack Exchange. Other symbols I have seen used for "is defined to be equal to" are three horizontal lines instead of two, and $=$ with either a triangle or "def" written directly above it. I have seen variants of these used by people who predate widespread knowledge of computer programming.

Building on this, it would be interesting to know the earliest uses of a special symbol for this (and what symbols were chosen). What do the symbols "=" and "==" mean in python? You'll need to complete a few actions and gain 15 reputation points before being able to upvote.

Upvoting indicates when questions and answers are useful. What's reputation and how do I get it? Instead, you can save this post to reference later. r - What are the differences between "=" and - Stack Overflow. What are the differences between the assignment operators = and <- in R?

I know that operators are slightly different, as this example shows x <- y <- 5 x = y = 5 x = y <- 5 x <- ... Furthermore, what is the difference between == and equals () in Java?. It's important to note that, main difference between == and equals in Java is that "==" is used to compare primitives while equals() method is recommended to check equality of objects.

String comparison is a common scenario of using both == and equals() method.
