The approximation sign "≈" I use for decimal approximations with tilde "~" being a rougher approximation. Tilde "~" I use to state a geometric shape is similar to another one ie a triangle of sides 3/4/5 is similar to a triangle with sides 30/40/50. I write ABC ~ A'B'C' where A'B'C' is a dilated version of the pre-image.

2015年6月4日 · It should be mentioned that there's more to tilde expansion than this. See the bash manual on Tilde Expansion. For instance, tilde is expanded when used in variable assignment (e.g. SOME=~) even though it's not the first character of a word then. –

The tilde refers to the application root directory, and will be translated correctly in control properties such as NavigateUrl. My understanding is that if you use it in plain-HTML tags, it will not be translated by ASP.Net.

2011年11月29日 · One use I've found for the tilde operator is for converting a fraction from some base into base-10. For instance, let's say you want to convert 0.01 from base-5 to base-10. The formula for doing so should look like this: (0 * 5^0) + (0 * 5^-1) + (1 * 5^-2)

2008年12月23日 · For others who found this question illuminating, I have a quick ~ example to share. The following snippet from the implementation of a paint method, as detailed in this Mono documentation, uses ~ to great effect:

As Sean Bright pointed out in a comment, the baseline tilde behavior regarding home directories is codified as standard behavior for POSIX-compliant shells. Additionally, the wordexp() C API function is specified to implement this behavior. Though, obviously, use with caution.

Tilde isn't anything special in the URLs. It's just another character like a %20 character or a -. Some web host companies use it to identify users by giving the users directories like /~(username)/

2019年6月23日 · $\tilde{T}$ is a very common construction... in abstract algebra. Not so much in linear algebra per se, but it fits into the general framework.
