This symbol (in English) informally[4] means "approximately", "about", or "around", such as "~30 minutes before", meaning "approximately 30 minutes before". [5][6] It can mean "similar to",[7] including "of the same order of magnitude as",[4] such as: "x ~ y" meaning that x and y are of the same order of magnitude.
In informal writing, a tilde is sometimes used before a number to mean “about” or “approximately.” For example, a sentence that reads I think my dog weighs ~20 pounds means I think my dog weighs about/around 20 pounds. This usage is likely based on the math usage of the tilde symbol to mean an approximate equivalency.
I chose a deep gratin-style dish to end up with approximately equal depth of fruit to topping. To the untrained eye the position may appear dull with approximately equal chances. All wars between armies of approximately equal capabilities are ghastly for those obliged to expose their flesh to storms of steel.
The main difference between the & and && operators is that the & operator is a bitwise operator, while the && operator is a logical operator. The & operator compares two values at the bit level, while the && operator compares two values logically.
"=" is used to assign the value. Example: x = 2, then value of x is 2. "==" is to show equality between values, Example x == y, here the value of y equal to x. = is used for assigning value eg- x=3 y=3 == is used for comparing whether the value is equal eg- if(x==y) comparing whether x is equal to y.
Definition for Difference in Math
The difference in math symbol is minus(-). Minuend is the first number in the subtraction sentence.
Approx. is a written abbreviation for approximately.
The magic sequence of keys Alt-255 typed at numeric keypad places an Invisible Character symbol into text. This character looks like a blank space in the program code and SAS output but is processed and printed by many programs as a valid text character.
On the Insert tab, in the Symbols group, click the arrow under Equation, and then click Insert New Equation. Under Equation Tools, on the Design tab, in the Symbols group, click the More arrow. Click the arrow next to the name of the symbol set, and then select the symbol set that you want to display.
(1) In mathematics, the tilde (~) stands for equivalence; for example, a ~ b means "a is equivalent to b" (not equal, but comparable). It also stands for approximation. Officially written as two tildes, one over the other, the single tilde has become acceptable; for example, ~100 means "approximately 100."
To create the tilde symbol using a U.S. keyboard, hold down Shift and press ~ . This symbol is on the same key as the back quote ( ` ), in the top-left portion of the keyboard under Esc. Doing the Alt code Alt +126 can also create a tilde.
How to Insert a Tilde Symbol (~) in LaTeX. You can write a tilde (sometimes called “twiddle”) in a LaTeX document by using \(\sim \) or $\sim$ (sim stands for similar). As an alternative you can use \texttildelow from thetextcomp package.
2) The ± symbol is used to indicate the precision of an approximation, the confidence interval, the standard deviation, or the error in a measurement.
Approximation. Before a number the tilde can mean 'approximately'; '~42' means 'approximately 42'. When used with currency symbols that precede the number (national conventions differ), the tilde precedes the symbol, thus for example '~$10' means 'about ten dollars'.
