Informix DataBlade API Programmer's Manual DataBlade API Function Descriptions

The invmuldbl() function multiplies an interval value by a numeric value.

mint invmuldbl(iv, num, ov)

	intrvl_t *iv;

	double num;

	intrvl_t *ov;

 



iv

is a pointer to the interval variable to multiply.


num  

is the numeric double value.


ov

is a pointer to the interval variable with a valid qualifier.

The invmuldbl() function multiplies the interval value in iv by num and stores the result in ov. The value in num can be either positive or negative.

Both the input and output qualifiers must belong to the same interval class: either the year to month class or the day to fraction(5) class. If the qualifier for ov is different from the qualifier for iv (but of the same class), the invmuldbl() function extends the result (as the invextend() function defines).
