Sending data using SMS-GSM module

I am working on a small home energy monitoring project. I have stored the values from my sensors in an array of datatype "double". Now i need to send these values at regular interval in form of SMS using my icomsat 1.1 gsm sheld for arduino. Is it possible to send an array directly through sms? I tried to use typecasting to change the datatype of my variable, but its not working.
Can anybody please share the method to send an array using GSM shield or code for typecasting the array to a form suitable for sending using sms via an Arduino GSM module.
