LPC546xx PLL

I use a LPC54608 board and I don't understand how PLL values are decoded. For example to generate an output frequency of 180Mhz the M value is 30 but it is turned into a MDEC value. I don't understand the pseudocode written into user manual of microprocessor. From an M value of 30 the MDEC value  is 8192 but with pseudocode I get another value.

Someone could help me to understand?

Thank you
