INFORMIX-ESQL/C Programmer's Manual ESQL/C Function Library

The decdiv() function divides two decimal type values.

mint decdiv(n1,  n2,  result)	/*  result  =  n1  /  n2  */

	dec_t  *n1;

	dec_t  *n2;

	dec_t  *result;

 



n1

is a pointer to the decimal structure of the first operand. 


n2

is a pointer to the decimal structure of the second operand. 


quotient  

is a pointer to the decimal structure that contains the quotient of n1 divided by n2. 

The quotient can be the same as either n1 or n2.

The file decdiv.ec in the demo directory contains the following sample program.

/*
* decdiv.ec *

The following program divides two DECIMAL numbers and displays the result.
