SYNOPSIS
typedef struct { int len; short *val; } mint;
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 arguments. sdiv is like mdiv except that the divisor is an ordi-
nary integer. msqrt produces the square root and remainder of its first argument. rpow calculates a raised to the power b, while pow cal-
culates 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.
