The asterisk symbol, often referred to as the “star” or “splat” symbol, is a symbol with multiple uses in the English language, mathematics, and other fields. In English, it is often used in a variety of different contexts, from referencing a footnote to indicating omission of a word. In mathematics, it is used to denote multiplication, and in computer programming, it is used to denote a pointer or wildcard character. The symbol has many different uses, depending on the context. Let’s take a closer look at some of the uses of the asterisk symbol.
Use in English
In English, the asterisk symbol is often used to denote a footnote or endnote. For example, if a sentence contains a number of words with an asterisk next to them, this indicates that more information can be found at the end of the document in the form of an endnote or footnote. The asterisk symbol is also used to indicate omission of a word or words, as in the phrase, “She was *a* good girl.” Here, the asterisk indicates that the word “very” is omitted from the sentence. Additionally, the asterisk symbol is used in dictionaries and other reference books to indicate that a word is irregularly spelled or has more than one meaning.
Use in Mathematics
In mathematics, the asterisk symbol is used to denote multiplication. For example, if we want to calculate 3 times 4, we can write this as 3 * 4 or 3×4. In this equation, the asterisk indicates that we are multiplying the two numbers together. The asterisk can also be used to denote raised to the power of, as in 4 * 2 = 16, which is equivalent to saying 4 squared equals 16.
Use in Computer Programming
In computer programming, the asterisk symbol is used to denote a pointer or wildcard character. A pointer is a special type of variable that stores a memory address. In C and C++, the asterisk symbol is used before a variable name to denote that it is a pointer. A wildcard character is a special character that can be used to represent any number of characters in a string. In many computer languages, the asterisk symbol is used as a wildcard to represent any character or string of characters in a search.
Use in Texting and Social Media
The asterisk symbol is also used in texting and social media. In texting, it is often used to represent a correction or addition to a phrase. For example, if someone types “I had a great time yesterday**”, the two asterisks indicate that the sender meant to add something else to the sentence, such as “with my friends”. On social media, the asterisk symbol is often used to indicate that a statement or phrase is sarcastic or humorous.
Use in Astronomy
In astronomy, the asterisk symbol is used to denote the presence of a star or other celestial body. For instance, if an astronomer is looking at a star chart and sees a symbol with an asterisk next to it, this indicates that there is a star or other celestial body in that location.
Use in Music
In music, the asterisk symbol is used to indicate where a note should be repeated. For example, if a musician sees an asterisk symbol next to a note on a sheet of music, this indicates that the note should be repeated until the end of the measure or phrase. Additionally, the asterisk symbol can be used to denote a certain technique that should be used when playing a note.
