If we take 12 and DIVIDE it by 7 we get about 1,714…

But is there a mathematical operator/symbol similar to DIVISION witch rounds the answer to the lowest whole number? In this case; one

and the opposite:

Is there a mathematical operator/symbol similar to DIVISION witch rounds the answer to the higest whole number? In this case; two

Thanks.

I think the op means an actual function, such as x^2 /3x or something. (just an example)
 
"Floor" and "ceiling" are "actual functions". If you mean something else you will have to explain what you mean by "function".

I know what you're thinking but those kinds of functions are mostly continuous and what the OP is looking for is a step function which is discontinuous at infinitely many points.

There is a reason why the Floor and Ceiling functions were constructed :wink:
 
Insights auto threads is broken atm, so I'm manually creating these for new Insight articles. In Dirac’s Principles of Quantum Mechanics published in 1930 he introduced a “convenient notation” he referred to as a “delta function” which he treated as a continuum analog to the discrete Kronecker delta. The Kronecker delta is simply the indexed components of the identity operator in matrix algebra Source: https://www.physicsforums.com/insights/what-exactly-is-diracs-delta-function/ by...
Fermat's Last Theorem has long been one of the most famous mathematical problems, and is now one of the most famous theorems. It simply states that the equation $$ a^n+b^n=c^n $$ has no solutions with positive integers if ##n>2.## It was named after Pierre de Fermat (1607-1665). The problem itself stems from the book Arithmetica by Diophantus of Alexandria. It gained popularity because Fermat noted in his copy "Cubum autem in duos cubos, aut quadratoquadratum in duos quadratoquadratos, et...
Thread 'Imaginary Pythagorus'
I posted this in the Lame Math thread, but it's got me thinking. Is there any validity to this? Or is it really just a mathematical trick? Naively, I see that i2 + plus 12 does equal zero2. But does this have a meaning? I know one can treat the imaginary number line as just another axis like the reals, but does that mean this does represent a triangle in the complex plane with a hypotenuse of length zero? Ibix offered a rendering of the diagram using what I assume is matrix* notation...
