功能强大的计算器软件qalculate下载解二元方程、积分..
Qalculate！ 是一款简单易用而且功能强大的计算器软件。Qalculate是一个功能强大的计算器，可以解决二元方程、积分、调用gnu,plot绘图等。
一个功能非常强大的计算器，不仅仅是计算器，竟然可以解决二元方程、积分、调用gnu
plot绘图等，比以前喜欢的rcalc更加强大多了！还有一个命令行下的版本qalc.
Qalculate! is not your regular software replication of the cheapest
available calculator. Qalculate! aims to make full use of the superior
interface, power and flexibility of modern computers.
The center of attention in Qalculate! is the expression entry, Instead of
entering each number in a mathematical expression separately, you can
directly write the whole expression and later modify it. Just enter an
expression as you would write it on paper, press Enter and voila!
The interpretation of expressions is flexible and fault tolerant, and if
you nevertheless do something wrong, Qalculate! will tell you so. Not fully
solvable expressions are however not errors. Qalculate! will simplify as
far as it can and answer with an expression.
In addition to numbers and arithmetic operators, an expression may contain
any combination of variables, units, and functions. These are immediately
accessible from the user interface — the menu bar, the managers, the
calculator keypad, and automatic completion.
Qalculate! also has some special tools to increase your efficiency,
including a number base conversion dialog and a simple plotting interface.
Although use of Qalculate! for simple calculations should be natural and
self-explanatory, reading the rest of the manual can help you maximize your
productivity and discover some maybe unexpected features. More advanced
users should read on and discover a large number of customization options
and the ability to create and modify your own variables, functions and
units directly from the user interface.
