Compiler is gcc 4.5.2 on Solaris11 Box

It prints fine however given the 2 different formulas it prints 2 different results.

kilometers = 1.609 * (miles + yards / 1760.0);
end result = A marathon is 42.185970 kilometers.


kilometers1 = 1.609 * (miles + yards / 1760);
end result = A marathon is 41.834000 kilometers.

From what I gather when yards is divided by a float it results in a float.
When yards is divided by an int it results in a int
As a float 385/1760 = .218
As an int .218 = 0
