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
