This calculator converts 32-bit and 64-bit binary strings into their floating point values (i.e. decimal values such as "3.14159..."). It can also convert the decimal number to a 32-bit and 64-bit binary string.

For example, the floating point (decimal) value of Pi is:

• 3.14159

The binary representation of Pi is therefore:

• 01000000 01001001 00001111 11010000

This calculator supports two-way conversions. To clarify what that means, here is an example of a two-way conversion:

• Float to Binary (3.14159 = 01000000 01001001 00001111 11010000)
• Binary to Float (01000000 01001001 00001111 11010000 = 3.14159)

This app is designed to help computer science and computer architecture students easily understand how a floating point value is calculated. For example: the binary string is color coded to help students differentiate between the sign, the exponent, and the mantissa. Another example: by long-pressing on an individual bit, this will activate an overlay that shows the user what happens when that specific bit is toggled on or off (try it out!).

This converter also supports other numerical systems or representations including: floating point, binary, hexadecimal, octal, signed integer, and unsigned integer numbers.

• Error calculation:
  • The calculator will calculate the bit scheme that most closely represents the "entered" value
  • The "actual" value shows the exact value of any given bit representation by the computer
  • The "difference" will calculate the "error" between "actual" and "entered" values
  • If the "accuracy" is 100%, than the "entered" value is represented exactly by the bit conversion
  • The green background span on the "actual" value represents which digits match with the "entered" value
  • The red background span on the "actual" value represents which digits do not with the "entered" value

Developed for the GPD XD Plus and tested on various Bluetooth gamepads. This app turns the joystick on your gamepad or game controller into a PC mouse. This is especially useful for those who connect their Android-based emulation machines (e.g. GPD XD+) to an external screen via HDMI out or screencasting.

The Joystick Mouse adapter works similar to the way the joystick on the GPD Win 1 and GPD Win 2 works in mouse mode.

• Perform short and long clicks.
• Variable mouse pointer speed based on joystick input.
• Perform actions such as: go home, go back, recent apps.
• Control volume, expand notification tray, launch power dialog.
• Scroll pages and navigate menus with D-Pad.

• Change mouse pointer style.
• Change mouse pointer color.
• Adjust mouse speed.
• Assign and configure button functions

• Android Nougat 7.0 or newer
• Android compatible game controller

An Android service that adds an overlay of the 'Recent apps', 'Home', and 'Back' buttons to the ZTE Axon 7 Android smartphone. This app was designed for the ZTE Axon 7, but it works perfectly on other Android devices.

This app solves a design flaw on the ZTE Axon 7's capacitive buttons. Most Android buttons light up so they are visible at night. Those buttons are usually spaced out from each other which prevents accidental input (for example: accidentally pressing 'home' instead of 'back'). The Axon 7's buttons are very close together and they are impossible to see at night because they do not light up. My software adds icons next to these buttons so that the user can get a good feel of where the buttons are in the dark.

I call this app "Guide Lights" instead of "Navigation Bar" because my intention was to use this app as 'inert icons' instead of 'functional buttons'. My reasoning for this is that I do not want the buttons to block touch input where the overlay is obstructing. However, I know a lot of users prefer actual buttons so I included the option to enable button functionality.

A 2D top-down simulation of a Forest Fire. It is a real-time, interactive simulation with replay features and a map editor.

You start with a randomly generated map of trees. Then you can set a virtual fire on any tree and watch how the fire propogates through the nearby trees. You can also generate rain and wind weather effects. Rain reduces the spread rate of the forest fire. Wind will affect the path of the fire, depending on the direction of the wind.

The map editor and generator allows you to create new maps. You can either manually place trees on the map or generate them randomly. You can also delete sections of trees and specify the size of the map.

The replay feature allows you to rewind to a specific point during the simulation or return back to the most recent point. When you rewind, you can change the outcome of the fire propogation by choosing different spots to propogate the spread of the forest fire. If you're impatient, you can increase the simulation speed. If you want to pay closer attention to how the fire spreads, you can decrease the simulation speed.

A Java-based floating-point calculator that supports two-way 32-bit and 64-bit precision conversions between decimal values and their equivalent binary representations. This was a team project with co-developer Latrice Sebastian.

• Floating point precision:
  • Single Precision
  • Double precision
• Conversions:
  • Float-to-binary
  • Binary-to-float

• Instant output:
  • No need to press enter
  • Values updated dynamically
• Formatted output:
  • Hide trailing zero bits
  • Remove space delimiters

• Half precision:
  • never listed as a features because it was buggy and did always produce the correct result.
• Single and double precision:
  • (2019) discovered that single and double precision are not always accurate after further testing. This is due to unaccounted loss of precision during the manual calculations for certains numbers. Development for this app has stopped for the time being but I have made an Android version of this calculator which simply uses built-in Java functions to obtain these values which have higher accuracy than this version.
