Need help on Fortran!

cre=1.0*(sum(j)-bit(ii,j)*lac(ii,ip))

the code above I get it from a fortran program. And it is a formula. But I just wondering what is the meaning of 1.0 over there?Is it same meaning as 1 times the blacket formula?Thanks.

Yes, you are correct. This is just multiplication of 1 on what is in the brackets. This method is used some times for converting from integer type to float. Check if those arrays are declared as integers and cre as float.
Cheers
