【實用工具app】Speedy Calculator|最夯免費app-綠色工廠好玩App

A version of calculator designed to achieve fast expression input and editing. Instead of having an array of buttons for user to press, the required calculations can be written using a simple text-box. This also allows copy/paste of expressions and answers.

[Usage]

The expression text ignores spaces, but sees difference between capital and lower-case letters.

Known expressions are:

a+b - Add "a" to "b"

a-b - Substract "b" from "a"

a*b - Multiply "a" and "b"

a/b - Divide "a" by "b"

a**b or a^b - Put "a" to the power of "b"

e - Exponent of 10. Can be used only with numbers, not variables. For example 1e3 = 1000.0

= - Variable assigning sign. For example "g=-9.81" will create a variable "g", equaling "-9.81". This variable will be added to [Menu] -> [Variables]

formula_name() - calculate the formula using the expression in parenthesis. For example "sin(30)" will equal to 0.5. A list of known formulas can be found at [Menu] -> [Formulas]
