Equation Solver

About

Floatr is a simple equation solving app that allows users to save named equations, removing the need to constantly search for that same equation again and again. 

Supported Operations

Floatr in its current state supports PEMDAS operations, the remainder operation (only with integers), and a few special unary operations:

• abs(x)
• round(x)
• rad2deg(x)
• log(x)
• ln(x)
• sin(x)/asin(x)
• cos(x)/acos(x)
• tan(x)/atan(x)

There are also a few pre-defined values:

• PI
• E

Assigning Variables

Variables are defined in an expression you create. A variable can be a combination of letters, numbers, and underscores, but the first character has to be a letter. When solving an equation, you must define a variable inside the variable table in three ways:

• Numbers
  • 11
  • -5
  • 1.12334
• Pre-defined variables
  • PI
• Expressions without variables 
  • PI^2
  • asin(sqrt(2)/2)
