This is an RPN (Reverse Polish Notation) calculator program. This works by pushing numbers to a stack, and then completing operations on the pushed numbers in the order that they were added to the stack.
|
|
|
|
Example: 4 [enter] 3 [enter] * [enter]
|
|
Will display 12 on the Current Stack (i.e. 4 * 3 = 12)
|
|
|
|
Many more math functions are available:
|
|
|
|
[Command] [Function]
|
|
q quit calculator (ctrl-c also works)
|
|
+ add the last two numbers on the stack
|
|
- subtract the last two numbers on the stack
|
|
* or x multiply the last two numbers on the stack
|
|
/ divide the last two numbers on the stack
|
|
% output the remainder of the division of the last two numbers on the stack (modulus)
|
|
clear or c clear the stack of all values
|
|
del or d remove the last number pushed to the stack (this can be repeated multiple times)
|
|
floor take the last two numbers from the stack, and push the lower number back onto the stack
|
|
ceil take the last two numbers from the stack, and push the higher number back onto the stack
|
|
round round the last number on the stack (follows conventional rules, 0.5 rounds up)
|
|
abs change the last number on the stack to it's absolute value
|
|
pow raise the number on the stack prior to the last input to the power of the last number input
|
|
Example: 3 [enter] 2 [enter] pow [enter] Output: 9
|
|
sqrt or v change the last number on the stack to it's square root
|
|
cbrt or v3 change the last number on the stack to it's cube root
|
|
ln change the last number on the stack to it's natural log
|
|
log change the last number on the stack to it's base10 log
|
|
sin change the last number on the stack to it's sine value (radians)
|
|
asin, sinh the same thing, but arc and hyperbolic instead
|
|
cos change the last number on the stack to it's cosine value (radians)
|
|
acos, cosh the same thing, but arc and hyperbolic instead
|
|
tan change the last number on the stack to it's tangent value (radians)
|
|
atan, tanh the same thing, but arc and hyperbolic instead
|
|
me pushes the machine epsilon value onto the stack
|
|
pi pushes pi onto the stack
|
|
tau pushes tau on to the stack
