In 1973, a transatlantic satellite link connected the Norwegian Seismic Array (NORSAR) to the ARPANET, making Norway the first country outside the US to be connected to the network.

mp(3MP) 					       Multiple Precision Library Functions						   mp(3MP)

NAME
mp, mp_madd, mp_msub, mp_mult, mp_mdiv, mp_mcmp, mp_min, mp_mout, mp_pow, mp_gcd, mp_rpow, mp_msqrt, mp_sdiv, mp_itom, mp_xtom, mp_mtox, mp_mfree - multiple precision integer arithmetic SYNOPSIS
cc [ flag... ] file... -lmp [ library... ] #include <mp.h> void mp_madd(MINT *a, MINT *b, MINT *c); void mp_msub(MINT *a, MINT *b, MINT *c); void mp_mult(MINT *a, MINT *b, MINT *c); void mp_mdiv(MINT *a, MINT *b, MINT *q, MINT *r); int mp_mcmp(MINT *a, MINT *b); int mp_min(MINT *a); void mp_mout(MINT *a); void mp_pow(MINT *a, MINT *b, MINT *c, MINT *d); void mp_gcd(MINT *a, MINT *b, MINT *c); void mp_rpow(MINT *a, short n, MINT *b); int mp_msqrt(MINT *a, MINT *b, MINT *r); void mp_sdiv(MINT *a, short n, MINT *q, short *r); MINT * mp_itom(short n); MINT * mp_xtom(char *a); char * mp_mtox(MINT *a); void mp_mfree(MINT *a); DESCRIPTION
These functions 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 mp_itom(n), which sets the initial value to n. Alternatively, mp_xtom(a) may be used to initialize a MINT from a string of hexadecimal digits. mp_mfree(a) may be used to release the storage allocated by the mp_itom(a) and mp_xtom(a) rou- tines. The mp_madd(a,b,c), mp_msub(a,b,c) and mp_mult(a,b,c) functions assign to their third arguments the sum, difference, and product, respec- tively, of their first two arguments. The mp_mdiv(a,b,q,r) function assigns the quotient and remainder, respectively, to its third and fourth arguments. The mp_sdiv(a,n,q,r) function is similar to mp_mdiv(a,b,q,r) except that the divisor is an ordinary integer. The mp_msqrt(a,b,r) function produces the square root and remainder of its first argument. The mp_mcmp(a,b) function compares the values of its arguments and returns 0 if the two values are equal, a value greater than 0 if the first argument is greater than the second, and a value less than 0 if the second argument is greater than the first. The mp_rpow(a,n,b) function raises a to the nth power and assigns this value to b. The mp_pow(a,b ,c,d) function raises a to the bth power, reduces the result modulo c and assigns this value to d. The mp_min(a) and mp_mout(a) functions perform decimal input and output. The mp_gcd(a,b,c) function finds the greatest common divisor of the first two arguments, returning it in the third argument. The mp_mtox( a) function provides the inverse of mp_xtom(a). To release the stor- age allocated by mp_mtox(a) use free() (see malloc(3C)). Use the -lmp loader option to obtain access to these functions. FILES
