Algebraic operators
Absolute value
!ABS
takes absolute values - no argument required.
yield
ABSyield !=yield !ABS
Arc-sine transformation
!ARCSIN v
forms an ArcSin
transformation using the sample size specified in the
argument which may be a number or another field.
In the example, for two existing fields
Germ
and
Total
containing
counts, we form
the ArcSin for their ratio (
ASG
) by copying the
Germ
field
and applying the ArcSin transformation using the
Total
field as
sample size.
Germ Total
ASG !=Germ !ARCSIN Total
Sine and Cosine
!COS s
and
!SIN s
takes cosine and
sine of the data variable with period s
having default 2pi; omit s if data is in radians,
set s to 360
if data is in degrees.
Day
CosDay !=Day !COS 365
Exponential
!EXP
takes antilog base e -
no argument required. (Use
!^0
to take logarithms (base e).)
Rate !EXP
Maximum, Minimum and Modulus
!MAX v
changes the data value to the value of
v
if it is less than the value of
v.
v
is either a number or another field.
!MIN v
changes the data value to the value of
v
if it is greater than the value of
v.
v
is either a number or another field.
!MOD v
changes the data value to the modulus of
v .
v
is either a number or another field.
yield !MAX 9
