Gimp Automatically Resizes

I need to create a cover for my book.

I set canvas width to 10.4325 inches, but Gimp automatically resizes it to 10.433 inches.

How can I stop this from happening?

One thing I notice is that when I frist insert the size: 10.4325 inches, then accept these values.
Next, I open canvas size again, it is not set to inches but automatically displays the values as pixels. When I then click inches again, I get 10.433 inches. 
Is this thus some type of calculation problem taking place?

Thank you,

Immortality

What you are seeing is presumably the result of arithmetic rounding. As GIMP works in pixels why don't you tackle the problem slightly differently. Decide how many pixels per inch (300?) you want for the printing and then multiply the width and height of your book cover in inches by this value and create an image of this size in GIMP. The size in inches or mm that GIMP shows for the image is irrelevant - assuming that you are not going to print from within GIMP (which is, perhaps, not the best program to print with). You may need to set the number of pixels per inch in GIMP if your printing program doesn't allow you to import an image and then specify the print size. For example you can insert an image into a LibreOffice Writer document and specify the size at which it should be printed regardless of the number of pixels or pixels per inch information stored in the image file (not that I am suggesting using Writer to print)
