What does tilde mean in math?
What does tilde mean in math?
approximately
As a mathematical symbol, the tilde means “approximately” and in logic it means “not.” The tilde is one of the 128 alphanumeric and special characters in ASCII, the most common standard for electronic text exchange.
What does ≃ mean?
≃ ( U+2243 ≃ ASYMPTOTICALLY EQUAL TO, LaTeX \simeq), a combination of ≈ and =, also used to indicate asymptotic equality. ≅ ( U+2245 ≅ APPROXIMATELY EQUAL TO, LaTeX \cong), another combination of ≈ and =, which is also sometimes used to indicate isomorphism or congruence.
What does ∼ mean in logic?
Given a proposition p, then ∼p (“not p”) is to count as false when p is true and true when p is false; “∼” (when thus interpreted) is known as the negation sign, and ∼p as the negation of p.
What does tilde mean in statistics?
has the distribution (of)
In statistics, the tilde is frequently used to mean “has the distribution (of),” for instance, means “the stochastic (random) variable has the distribution (the standard normal distribution).
What does (~) mean in statistics?
In set theory, means that there is an equivalence relation between and . 4. In statistics, the tilde is frequently used to mean “has the distribution (of),” for instance, means “the stochastic (random) variable has the distribution (the standard normal distribution).
How do you calculate tilde?
For example, if you have the integer 0 represented by eight bits (one byte) 0000 0000 , the tilde operation ~0000 0000 results in the value 1111 1111 which is the integer value -1 . The general formula to calculate the tilde operation ~i on an integer value i is ~i=-i-1 .
What does ≡ mean in math?
identical to
≡ means identical to. This is similar to, but not exactly the same as, equals. Therefore, if in doubt, stick to =. ≈ means approximately equal to, or almost equal to. The two sides of a relationship indicated by this symbol will not be accurate enough to manipulate mathematically.

What does tilde mean in logic?
logical negation symbol
The logical negation symbol is used in Boolean algebra to indicate that the truth value of the statement that follows is reversed. The symbol resembles a dash with a ‘tail’ (¬). The arithmetic subtraction symbol (-) or tilde (~) are also used to indicate logical negation.
