Blend modes math equations

[denica001]

Hi everyone, one of my top questions ever about photoshop is where could I found some documentation about the real math equations and algorithms that plays inside blend modes operations??

Does anyone now any site, any book, any useful information wide deep inside the core of photoshop?

Thanks.
