Need help with Sim908 GPS code

[mastero]

Hello friends,

I am building a SIM908 GPS module with SMS control.

The problem i am facing is i need to convert deg min.min latidude to deg decimal.

I have the formula but dont know how to put it in the code

This is what the GPS module sends 4,1234.123456,N,7890.123456,E,123123.000,A,A

I can receive it and resend it as it is with the below code but i need some maths to be done before sending.

eg: 1234.123456 div by 100 = 12.34123456

Once i have this i need to divide the numbers on the right of the decimal by 60

eg: 34123456 div by 60 = 568724.266666

now i want this number to be sent out 12.568724

How can i do it below is my code.
