C program to convert binary fraction to decimal

Question

I have 64 bits that are all supposed to be behind the decimal (0.000.....0), how can I convert this binary fraction to a decimal in C preferably without a lot of iterations or loops.

For example:

I have int x = 2218 which is 100010101010 thats supposed to represent 0.100010101010 converted into a decimal (in this case it would be 0.54150390625)
