The dectodbl() function converts a decimal type number into a C double type number.

mint dectodbl(dec_val,  dbl_val)

	dec_t  *dec_val;

	double  *dbl_val;

 



dec_val  

is a pointer to a decimal structure whose value dectodbl() converts to a double type value.


dbl_val

is a pointer to a double type where dectodbl() places the result of the conversion. 

The floating-point format of the host computer can result in loss of precision in the conversion of a decimal type number to a double type number.
