	1 .TH ZMOD 3 libzahl
	2 .SH NAME
	3 zmod - Calculate the modulus of two big integer
	4 .SH SYNOPSIS
	5 .nf
	6 #include <zahl.h>
	7
	8 void zmod(z_t \fIremainder\fP, z_t \fIdividend\fP, z_t \fIdivisor\fP);
	9 .fi
	10 .SH DESCRIPTION
	11 .B zmod
	12 calculates the remainder of a
	13 .I dividend
	14 and a
	15 .IR divisor ,
	16 and stores the result in
	17 .IR remainder .
	18 That is,
	19 .I remainder
	20 gets
	21 .I dividend
	22 Mod
	23 .IR divisor .
	24 .P
	25 The result
	26 .RI ( remainder )
	27 is negative if and only if the
	28 .I dividend
	29 is negative. To be more precise,
	30 a Mod b = (\|a\| Mod \|b\|) sgn a for all integers a
	31 and b.
	32 .P
	33 It is safe to call
	34 .B zmod
	35 with non-unique parameters.
