With this program you can put loads of numbers into some formulae.
Start the program with the usual double click. If you need
some details (what happens if I click on this button?) Acorns
interactive Help program may give you the answer.
Functions implemented:
~~~~~~~~~~~~~~~~~~~~~~
a) prefix functions:
Symbol Meaning Autom. error calc.?
----------------------------------------------------------------------------
- Minus yes
/ 1/... (invert) yes
SQR ...^2 yes
SQRT square root yes
LN nat. logarithm yes
EXP exponential function yes
COS cosine yes
SIN analogue yes
TAN dito yes
ASIN arc sine yes
ACOS guess... yes
ATAN yes
SINH hyperbolic sine yes
COSH hyperbolic cosine yes
TANH hyperbolic tangent yes
ABS absolute no
SUM sum of all values in table no
IDX(tb) indices of table tb = 0
IDX(sk) table 1,2,..sk (sk: scalar) = 0
INT "discrete integral" no
FFTH Fourier trafo (to frequencies) no (table length must be
FFTR Fourier trafo (back) no a power of 2!)
b) implemented operators:
Symbol Meaning Automatic err.
---------------------------------------------------------------
+ Addition yes
- Subtraction yes
* Multiplication yes
/ Division yes
^ Power yes
: Shifting operator: shifts table by the no
given number of lines to the top.
! Selection operator: yields elements with no
the given indices.
? Exclusion operator: yields elements not no
given in the second table.
& concatenates two tables no
% partial derivative with respect to the yes
given variable.
