￭ Common variables
List of common variables. All of the common variables are listed, no
matter whether they possess a value or not.
You will find a detailed description of all of the variables in chapter
28.4.3.3, page 296.
28.4.3.2 Mathematical functions
The following mathematical functions can be utilized in a calculation for-
mula:
Function Description
y^z Power function
Example: 4^2 = 16
SQRT(X) square root of X
Example: √(EP1)
ABS(X) absolute value of X
Example: ABS(C00); in order, e.g. with reweighings, to
convert the negative sample size to a positive value for
later calculations
LN(X) natural logarithm of X
LOG(X) decimal logarithm of X
FRAC(X) Fraction of X
Example: FRAC(2.5971) = 0.5971
INT(X) integer part of X
Example: INT(2.5971) = 2
TST(X,Y) Test function
If invalid variables (e.g. missing endpoints) occur in a cal-
culation, then these can be replaced with a valid value
by using this function. In this way invalid results can be
avoided.
￭ Syntax:
– X = variable to be tested
– Y = replacement value
