Functions and commands 131

Division

Quotient Returns the integer quotient of the Euclidean division of two

integers.

iquo(Intgr1, Intgr2)

Example:

iquo(63, 23) returns 2

Remainder Returns the integer remainder from the Euclidean division of

two integers.

irem(Intgr1, Intgr2)

Example:

irem(63, 23) returns 17

MOD p For the three integers a, n, and p, returns a

modulo p in

[0, p−1].

powmod(a, n, p,[Expr],[Var])

Example:

powmod(5,2,13) returns 12

Chinese

Remainder

Integer Chinese Remainder Theorem for two equations. Takes

two vectors of integers, [a p] and [b q], and returns a vector

of two integers, [r n] such that x ≡ r mod n. In this case, x is

such that x ≡ a mod p and x ≡ b mod q; also n=p*q.

ichinrem([a,p],[b,q])

Example:

ichinrem([2, 7], [3, 5]) returns [-12, 35]

Polynomial

Find Roots Given a polynomial in x (or a vector containing the

coefficients of a polynomial), returns a vector containing its

roots.

proot(Poly)

or proot(Vector)

Example:

proot([1,0,-2]) returns

[-1.41421356237,1.41421356237]
