METAMASK WALLET DIDNT GET THE TOTAL AMOUNT OF TOKEN CREATED IN WALLET

I recently deployed a contract on the binance smart chain network and i wanted to create a total of one billion token but instead of a total of 10000000000 to be created i got on 0.1 one after deploying the contract. please i am confused as i dont know what to do now about it . please i also included the code thta i used to create theh token.

please i need assitance.
