SYNOPSIS

madd(a, b, c)
msub(a, b, c)
mult(a, b, c)
mdiv(a, b, q, r)
min(a)
mout(a)
pow(a, b, m, c)
gcd(a, b, c)
rpow(a, b, c)
msqrt(a, b, r)
mint *a, *b, *c, *m, *q, *r;
sdiv(a, n, q, r)
mint *a, *q;
short *r;
mint *itom(n)
DESCRIPTION
These routines perform arithmetic on integers of arbitrary length. The
integers are stored using the defined type mint. Pointers to a mint
should be initialized using the function itom, which sets the initial
value to n. After that space is managed automatically by the routines.
madd, msub, mult, assign to their third arguments the sum, difference,
and product, respectively, of their first two arguments. mdiv assigns
the quotient and remainder, respectively, to its third and fourth argu
ments. sdiv is like mdiv except that the divisor is an ordinary inte
ger. msqrt produces the square root and remainder of its first argu
ment. rpow calculates a raised to the power b, while pow calculates
this reduced modulo m. min andmout do decimal input and output.
The functions are obtained with the loader option lmp.
DIAGNOSTICS
Illegal operations and running out of memory produce messages and core
images.
