I am getting × in alert. I need to get × as result. Anybody knows or faces this problem? Please update your suggestions.
I usually use geometric block to do multiplication. $4\times 5$ is the number of $1\times 1$ blocks inside a rectangle with sides $4$ and $5$ that is $20$ $1\times 1$ blocks. in the case of $0.5\times 0.5$ we have a square with side $0.5$ and we want to know the number of $1\times 1$ blocks inside that.
arithmetic - 0.5 times 0.5 equals 0.25, but how does this work with ...
"Infinity times zero" or "zero times infinity" is a "battle of two giants". Zero is so small that it makes everyone vanish, but infinite is so huge that it makes everyone infinite after multiplication. In particular, infinity is the same thing as "1 over 0", so "zero times infinity" is the same thing as "zero over zero", which is an indeterminate form. Your title says something else than ...
Someone recently asked me why a negative $\times$ a negative is positive, and why a negative $\times$ a positive is negative, etc. I went ahead and gave them a proof by contradiction like this: As...
Bonus 2: repeating a 2D array this way takes a little bit more work, converting to rows a few times before wrapping back to the desired dimensions. You can of course use LET to keep things tidy if you don't want to define the array twice:
The solution is to restore the table N times by using UNDROP; and it only works if there is no table with the same name. N is a number of times the table is recreated using CREATE OR REPLACE; and time travel doesn't work as CREATE OR REPLACE drops the table and recreates it. I have created a table with some dummy data to test it.
