Calc v.3.03

Calc is a Java calculator for MIDP or J2ME devices, such as a Java-enabled mobile phone or PDA. It was developed on a Sony Ericsson T610, which was my first Java-enabled phone but which has such a pitiful built-in calculator that I was compelled to develop this application.

Calc works much like a good old HP calculator with RPN logic, but the stack has 16 elements and you can see many of the elements on the stack simultaneously. I have chosen to use RPN logic (Reverse Polish Notation), because operating it requires less keys, you need only ENTER instead of “(“, “)” and “=”. Additionally, being able to store and see intermediate results on the stack is very advantageous.

The following MIDP phones/devices have been tested with Calc v3.00 and later
versions:

• Sony Ericsson T610¹,
  T630¹, Z520i^1,N,
  Z600¹, Z800^1,2,N, Z1010, W600i,
  W800i^1,2,N, W810, K300i¹, K510i,
  K700i^1,2,N, K750i, K800i: Tested OK

• Sony Ericsson M600i: Tested OK. Awkward entering of
  numbers, ENTER and +, but the menu works fine using the touch-screen.

• Nokia 3230^1,N, 5140i,
  6020^N, 6103,
  6230i^1,2,N, 6265^1,N,
  6600^1,N,
  6630^1,N, 6670^1,N,
  6680^1,2,N, 6681^1,N,
  E60^1,2,N, N70^1,2,N, N73,
  N80^1,2,N: Tested OK

• Nokia N-gage: Only showing half the screen
• Motorola Razr V3¹,
  V180, V220, V547¹, V557, C380, C390, C650: Tested OK

• Siemens A65^1,S, C75^1,S,
  SX1^1,N, AX72^S, S65: Tested OK

• BenQ-Siemens EF81: Tested OK
• Samsung Z500^1,2, SGH-D407, SGH-t519, SGH D600:
  Tested OK

• Samsung E900: Tested almost OK. Problem with HEX input
• LG U880²: Tested OK
• Sharp 770sh¹: Tested OK
• Palm Zire 72: Tested OK. By using IBM’s WebSphere Everyplace Micro Environment it should run on every device that’s supported by the VM, e.g. Palm’s Tungsten T5, Tungsten E2, LifeDrive or Treo 650
