## What is LFunCalc?

LFunCalc is a function calculator that formulas are displayed and entered as a list.
Just after a formula is entered, the result is displayed without tapping enter key.
A formula name is assigned to each input line and can be referenced as a variable in the following formulas.
When a formula is changed, the value of the other formula referencing it is updated too. 
LFunCalc is also useful as a tool of parameter study.

Note) LFunCalc is not a spreadsheet application.
