Arduino Capabilities - Lengthy equations?

i wondering if arduino platform capable of need, think is, want check. i need take 3 inputs sensors, put them through rather long equation, multiply time, , arrive @ final value.  is arduino capable of processing long equation, on , on again, display value?   when "long equation", mean (or longer): ((((x/y+z)^2)/((m+n/p)^3))^(1/2)+((5-g/h)/(b*h))^2)/(1-(x+y)/z)+(1425+r/m*c*a)^2/(((b*c*100/d)*2)^(1/2)))*t thanks (i'm still new this, please excuse ignorance) hey there. far know, should fine. have make sure of though, use right data type. example, unsigned int takes relatively little memory store, has range of 0 32000. float, on other hand between 3.4028235e+38 , -3.4028235e+38 , has 6-7 digits of resolution, including decimals uses more room. what might encounter pause or slowdown in code due intensive math have do. if sampling data only, say, once every 30 min, should fine. in conclusion, dog can dig, backhoe faster. arduino it, thats no...

Pinout for Port Registers on Arduino Mega??

hi there, my arduino program uses port registers extensively (portb, portd, etc).  currently, merging work of several arduino diecimilas onto 1 arduino mega can't find conclusive information how mega pinout corresponds higher port registers (porte, portf, etc).  i see port registers referenced on 1280 data sheet , in arduino avr code libraries, use assistance. would please point me in right direction? thank you! christopher baker christopherbaker.net i posted spreadsheet here may help: http://spreadsheets.google.com/pub?key=rthw_r6evl140ks9_g8gpka&gid=0 Arduino Forum > Forum 2005-2010 (read only) > Software > Syntax & Programs > Pinout for Port Registers on Arduino Mega?? arduino
