Need a more suitable number type for statistical calculations

hello everyone, I want to do some statistical calculations, so my numbers are very small(between 0 and 1) with massive multipications which makes them even smaller i was using double type for my work but i notice it only stores 5 digits of my number and for larger numbers it stores the power of 10. So it sure leads to a really big error in the final answers. How can i use more accurate types numbers? Thanks for the help

sina, MATLAB does NOT store only five digits. Please see the help for the format command, and read
