Explanation 
Example 
+ 
summation 
x+y 
c1+c2+c7 calculates the sum of the columns 1, 2, and 7 
 
subtraction 
xy 
r5r7 computes the difference between row 5 and 7 
* 
multiplication 
x*y 

/ 
division 
x/y 

# 
modulo 
x#y, the modulo function returns the remainder of integer division of round(x)/round(y) 
c3#5 returns the values in column 3 modulo 5 
^ 
exponentiation 
x^y , x,y..any real values 

() 
parenthesis 
parenthesis can be used to change operator precedence 
(c1+c2)*(c3+c4) is different from c1+c2*c3+c4 
ABS 
absolute value 
abs(x), x..any real number 

ARCCOS 
inverse cosine 
arccos(x) 

ARCSIN 
inverse sine 
arcsin(x) 

ARCTAN 
inverse tangens 
arctan(x) 

COS 
cosine 
cos(x), x..angle in radians 
cos(c1) returns the cosine of the values in column 1 (assuming that the column contains angles measured in radians) 
EXP 
exponent 
exp(x) 

FRAC 
decimal part of a real number 
frac(x) 
frac(3.822) returns the value 0.822 
GAUSS 
random number 
generates normally distributed random numbers with zero mean and unit standard deviation 
c1:=0.2*gauss+6.5 fills the column 1 with normally distributed random numbers having a mean of 6.5 and a standard deviation of 0.2 
INT 
integer part of a real number 
int(x) 

LG 
decadic logarithm 
lg(x) 

LN 
natural logarithm 
ln(x) 

MEAN 
returns the mean of a list of columns or rows 
mean(list), the list contains a list of columns or rows reparated by commas; a range of neighboring columns/rows may be abbreviated by the ':' sign. 
mean(r8:10,r5) calculates the mean of the rows 5, 8, 9, and 10. 
NDDENS 
density of the standard normal distribution 
nddens(x) 

NDINT 
integral of the standard normal distribution from infinity to x 
ndint(x) 

NDQUANT 
quantile of the standard normal distribution for a probability x 
ndquant(x) 

RAND 
uniformly distributed random numbers 
random(x), x..amplitude of noise (mean = 0.0) 
rand(8) creates uniformly distributed random numbers in the range of 4 to +4 
ROUND 
rounding to integer 
round(x) 

SIGN 
returns the sign of variable x 
sign(x) 

SIN 
sine 
sin(x), x..angle in radians 
sin(c1+pi/2) returns the sine of the values in column 1 plus pi/2 (assuming that the column contains angles measured in radians) 
SQR 
square 
sqr(x) 

SQRT 
square root 
sqrt(x), with x >= 0. Negative numbers generate an error message 

SUM 
returns the sum of a list of columns or rows 
sum(list), the list contains a list of columns or rows reparated by commas; a range of neighboring columns/rows may be abbreviated by the ':' sign. 
sum(c2,c8:11) calculates the sum of the columns 2, 8, 9, 10, and 11. 
TAN 
tangens 
tan(x), x..angle in radians 
tan(c4) returns the tangens of the values in column 4 (assuming the column contains angles measured in radians) 
VAR 
returns the variance of a list of columns or rows 
var(list), the list contains a list of columns or rows reparated by commas; a range of neighboring columns/rows may be abbreviated by the ':' sign. 
var(c1:4,c7,c9) calculates the variance of the columns 1, 2, 3, 4, 7, and 9.
