- Difference between ≈, ≃, and ≅ - Mathematics Stack Exchange
The symbol ≅ is used for isomorphism of objects of a category, and in particular for isomorphism of categories (which are objects of CAT) The symbol ≃ is used for equivalence of categories At least, this is the convention used in this book and by most category theorists, although it is far from universal in mathematics at large
- Definition of the approx. symbol - Mathematics Stack Exchange
$\begingroup$ It’s not exactly equal, so the correct symbol to use is $\approx$, not $ = $ You could use $ = $, but only when you use $\pi$ rather than its decimal approximation $\endgroup$ – KM101
- When should we write $\\approx$ (approximately symbol)?
Suppose we have to work with approximate numbers up to the second order, i e , with two decimal places
- When to use congruent vs approximately? - Mathematics Stack Exchange
The symbol U+2248 “≈” denotes, according to the standard, the relation “is approximately equal to” This is an intentionally vague relation; the standard adds: “It depends on the user whether an approximation is sufficiently good Equality is not excluded ”
- Different use of approximate equality symbols
I have been wondering for a long time whether there is a unequivocal way to define and use the symbols commonly adopted for an approximate equality between two quantities I am a physicist, and I often see them used interchangeably and more or less only accordingly to the taste of the author or lecturer
- What is the correct symbol for equal-rounded?
$\begingroup$ You mentioned in a comment above that using the symbol $\approx$ concerns you because it leaves out information such as the level of precision and accuracy But being in favor of using $1 17 = 0 0588\ldots $ as an alternative trades one ambiguity for another
- Is there a greater than about symbol? - Mathematics Stack Exchange
To indicate approximate equality, one can use ≃, ≅, ~, ♎, or ≒ I need to indicate an approximate inequality Specifically, I know A is greater than a quantity of approximately B Is there a way to
- Approximation symbol: Is $\\pi \\approx 3. 14\\dots$ equivalent to $\\pi \\fallingdotseq 3. 14\\dots$? - Mathematics Stack Exchange
Any mathematical notation is ok as long as it is common knowledge in your community For instance, I believe I fully understand the meaning of the $\approx$ symbol However, I haven't ever seen the second symbol you provided To be on the sure side you
