Functions and commands
Returns the nth prime number less than 10000.
ithprime(Intg(n))
Returns the next prime or pseudo-prime after an integer.
nextprime(Intg(a))
Returns the prime or pseudo-prime number closest to but
smaller than an integer.
prevprime(Intg(a))
Compute's Euler's totient for an integer.
euler(Intg(n))
Returns the integer quotient of the Euclidean division of two
integers.
iquo(Intg(a),Intg(b))
Returns the integer remainder from the Euclidean division of
two integers.
irem(Intg(a),Intg(b))
n
Returns a modulo p in [0;p−1].
powmod(Intg(a),Intg(n),Intg(p),[Expr(P(x
))],[Var])
Returns the Chinese remainder of two lists of integers.
ichinrem(LstIntg(a,p),LstIntg(b,q))
Returns all computed roots of a polynomial given by its
coefficients. (It may not work if roots are not simple.)
proot(Vect||Poly)
With an integer as third argument, returns the coefficient of a
polynomial of degree given in the third argument. With no
third argument, returns the list of coefficients of the
polynomial.
coeff(Expr,[Var],degree)
Returns the list of divisors of a polynomial or a list of
polynomials.
