In Computer Programming language, tilde(~) is called bitwise supplement operator.
Permit say, x is an Integer.
So, the cost of ~x can be -x-1.
Example :
1.) if x = 10 then
~x = -eleven;
2.) if x = 0 then
~x = -1;
3.) if x = -10 then
~x = 9;
Explanation :
while x = 10, then its binary representation could be 0000 1010 and now if we compute the cost of ~x(by way of inverting all of the bits) , we will get binary representation 1111 0101 which is now equal to -eleven
This has happened because inverting all of the bits will always trade the sign of an integer.
That’s why we usually gets the value of ~x through complementing all of the bits and subtracting 1 from it.
Why Subtracting 1 ?? As we all understand terrible of a variety of is received via complementing that quantity and adding 1 to that quantity.
In Maths,I knew the symbol “~” is known as as tilde & used for approximation in Mathematics.
In Spanish, it is used handiest on pinnacle of an N to provide a new letter, Ñ, which has a new sound.
In Portuguese, it modifications the way A and O are pronounced, àand Õ, nevertheless the ones sounds however with a more nasal sound.
Hope this may assist you.
