The tilde (~) is a grapheme which has several uses, described below. The name of the character comes from Spanish, from the Latin titulus meaning a title or superscription, and is pronounced "TILL-duh" (IPA /'tɪldə/) or "TILL-day". It was originally written over a letter as a diacritic (see below), but has since acquired a number of other uses as a character in its own right. In this capacity (especially in lexicography) it is also sometimes known as the swung dash (usually lengthened to ⁓).

It is also worth mentioning that in Spanish, the word tilde does not only refer to the ~ symbol as in English; the accent mark over vowels (e.g. é) is also called a tilde in Spanish. Diacritic use. In languages, tilde is a diacritic mark (~) placed over a letter to indicate a change in pronunciation, such as nasalisation.

In the International Phonetic Alphabet (IPA), the tilde is used over a symbol to mark nasalization and through a symbol to mark velarization.

It is sometimes used as punctuation (instead of a hyphen or dash) between two numbers, to indicate that they are a range, Japanese and other Asian languages almost always use this convention, but it is often done for clarity in other languages as well. For example: 12~15 means "12 to 15", ~3 means "up to three" and 100~ means "100 and greater". In Japanese, the tilde is also used to separate a title and a subtitle in the same line.

In mathematics, the tilde, often pronounced "twiddle," is often used to denote an equivalence relation between two objects. Thus x ~ y means x "is equivalent to" y (Note that this is quite different from stating that x equals y). Especially, it can be used to denote the asymptotical equality of two functions. For example, f(x) ~ g(x), means that limx→∞ f(x)/g(x) = 1.

In English, it is often used to mean "approximately". Therefore, ~10 would be "about 10". Similar symbols are used in mathematics, such as in π ≈ 3.14, "π is about equal to 3.14". Since the double-tilde (≈) is not available from the keyboard, the tilde (~) became a substitute when typing. There is also a triple-tilde (≋), which is used to show congruence. ComputingIn Unix shells, the tilde indicates the current user's home directory (e.g., /home/username). When prepended to a particular username, it indicates that user's home directory (e.g., ~janedoe for the home directory of user janedoe, typically /home/janedoe). When some Unix shell commands overwrite a file, they can be made to keep a backup by renaming the original file as filename~.

Used in URLs on the World Wide Web, it often denotes a personal website on a Unix-based server. For example, [1] might be the personal web site of John Doe. This mimics the Unix shell usage of the tilde. However, when accessed from the web, file access is usually directed to a subdirectory in the user's home directory, such as /home/username/public_html or /home/username/www.

It is used in the Perl programming language as part of the pattern match operators for regular expressions:
$a =~ /regex/ returns true if the variable is matched.
$a !~ /regex/ returns false if the variable is matched.

The popularity of Perl's regular expression syntax has led to the use of these operators in other programming languages, such as Ruby.

In the C and C++ programming languages, the tilde character is used to invert the bits of an integer. In C++, the tilde is also used as the first character in a class's method name (where the rest of the name must be the same name as the class) to indicate a destructor - a special method which is called at the end of the object's life.

In the D programming language, the tilde is used as an array concatenation operator, as well as to indicate an object destructor.

certificate是啥意思啊

参考技术A Certificate是证书、文凭、发给证书的意思，certificate作名词表示证书、文凭、合格证书的意思，那作动词，可以表示发给证明书、用证书证明的意思，certificate总共可以划分为4个音节【cer】、【ti】、【fi】和【cate】，cer是开音节，发音为【s?】，第二个音节发音为【t?】，第三个音节发音为【f?】，第四个音节发音为【k?t】，重音在第二个音节上，也就是ti上，所以这个单词的读音是【s??t?f?k?t】，这是英式发音，美式要把r的音发出来【s?r?t?f?k?t】；

certificate的词根为certify，表示证明的意思，加上名词后缀ate，y变i再加c，用作证明的东西，就是证书，marriage certificate，结婚证，divorce certificate，离婚证，那学校发的证书是什么，当然毕业证，所以certificate也可以表示一个人的文凭，同样如果是企业的证书，就是许可证、合格证的意思，校长给我颁发毕业证，The headmaster certificated me，certificate你学会了吗？
