How is voting power calculated in cosmos ?

[ghost]

I am using Cosmos SDK Version 0.42.4, I am concerned about how voting power is calculated. I need to make some changes on the staking module that would actually affect the voting power.I have gone through the x/staking/keeper/validator.go which has lots of functions to manage validators. But couldn't find the exact calculation. Any help is appreciated.
