Swep rounds per seconds to SWEP.Primary.Delay help?

What number do I put for SWEP.Primary.Delay if it’s in seconds for realistic guns?
For example, an AK47 fires 600 rounds per minute. 600 divided by 60 (1 minute) = 10, so it fires 10 bullets per second (If I’m right, but I’m somewhat bad at math). How would I write that into the code? Would it .1, .01, etc…
