iClose() misnamed?

iClose() appears to be misnamed. In "Hungarian notation", the "i" implies that the value returned by iClose() is an integer. However, iClose() returns data of type double. Therefore, iClose() would be more aptly named dbClose().

How would you interpret Apple Computers' iPod then?
 
Point well taken. I noticed the "i" is a prefix for the names of other indicator functions, such as iMA() and iBands(). I guess the "i" means the value returned by these functions depends on the value of the index parameter.
