Dear all,

I am looking for 32 bit controller in arduino platform. I found arduino Due only one model in 32 bit controller. Is my program / project involve double precision floating point calculation Which micro controller suit.
Is there any other controller in cheaper price which do double precision floating point calculation,
The arduino mega / due uses more no of pins than actual application so i need controller with min IOs , 10 analog ios, do double precision floating point calculation.

Please suggest me relevant model available, if yes share link to purchase

How about Teensy3.1 PJRC Store programmable from Arduino IDE. Digital pins are 5V tolerant (not sure about analogue pins though) and >10 analogue pins.
