How to calculate a Modulo? - Mathematics Stack Exchange
2018年2月28日 · For example, as above, $7 \equiv 2 \mod 5$ where $5$ is our modulus. Another issue is that of inverses ...
How can I find a mod with negative number? [duplicate]
I know how to solve mod using division i.e. $$11 \mod 7 = 4$$ For this I did a simple division and took its remainder: i.e. $$11 = 7 \cdot 1 + 4$$ Where $11$ was dividend, $7$ divisor, $1$ quotient and $4$ was remainder. But I have a problem with: $$-11 \mod 7 = 3$$ How come it is $3$? I cannot figure this out using division but if it is ...
The right way to write modulus equation? - Mathematics Stack …
$5 = 1 \mod 2$ This is the same thing as the previous one, just typeset differently. Do take care to note the added spacing; this ensures that this notation isn't confused with the following notation. I would guess this style is fairly uncommon. $5 \bmod 2 = 1$ This is the operator form of $\bmod$.
What is modulo arithmetic - Mathematics Stack Exchange
2011年11月9日 · d * 13 = 1 mod 1680 This is from how to make a public and private key pair. The answer is 517 apparently and I can get that from wolfram. I assume mod is %, but that doesn't seem to work out. I've also seen that this could me mod( 1, 1680 ) which supposedly equals . mod( m, n ) = m - n ( m / n ) But for that I get 1 and then 1 / 13 is obviously ...
What is the function "mod" - Mathematics Stack Exchange
2015年7月4日 · It is a reimander calculation In the standard format mod(8,4) equals 0 because there is no reimander in 8/4 but for mod(8,6) equals 2 because there is a reimander. It's just the first number divided by the second and the reimander that comes from it.
modulo question - Mathematics Stack Exchange
$\begingroup$ In math the meaning of 'mod' differs from its meaning in programming. The programmers primarily see 'mod' as a binary remainder operator that spews out an integer as its value. For them the mathematicians 'mod' may be best interpreted as a comparison operator, i.e. one that has true/false as its value.
is there a formula for modulo - Mathematics Stack Exchange
2022年6月16日 · (And, frankly, if there were a formula for mod in terms of sine, which there probably is with a sufficient amount of cleverness, it's sure to be very boring and artificial.) $\endgroup$ – anon Commented Feb 14, 2014 at 4:32
What is the difference between Modulus, Absolute value and …
As far as I know, I've never seen Absolute Value referred to as modulus, though wikipedia does acknowledge this use. Modulus and modulo both refer to the remainder operation. Generally speaking, "$5 \mod 7$" is read "$5$ modulo $7$," where the modulus is $7$. It's ultimately a matter of which you prefer to use.
How to read mod operation? (remainders and congruences)
2021年10月30日 · Note that $\LaTeX$ has built-in commands for traditional notation, viz. \pmod and \bmod and \mod. For example, 7\equiv 2\pmod 5 $\rightarrow 7\equiv 2\pmod 5\ \ $ $\endgroup$ – Bill Dubuque
Is it possible to do modulo of a fraction
For Example: 3 + 4 = 7, but 7 mod 7 = 0, thus 3 + 4 mod 7 = 0 mod 7, and 0 is an element of the set. 3 * 4 mod 7 = 12 mod 7 = 5 mod 7, and 5 is an element of the set. Now 1/2 means the inverse of 2 (in the multiplicative sense) This means that 2 times what number gives yields 1 or remainder 1? ( think of the normal integers. 5 * 1/5 = 1 )
