This function is great
if you want to slightly change the position of your data
for display purposes.
This powerful feature lets you quickly
and easily create new parameters based upon old ones. This is perfect
for those experiments where you need a ratio of one parameter
to another.
You can easily create a new parameter
or overwrite an existing parameter. You have the option
of using either a simple or formula calculation as the equation
for using parameter math. In the simple parameter math option,
the calculated parameters can be a function of two pre-existing
parameters or one pre-existing parameter and a constant.
By using the formula parameter math option,
you have the advantage that you can combine multiple parameters
and multiple different calculations in a single formula.
Formulas are entered as mathematical equations, where the
parameter number is represented by Pn, where n
is the parameter number. Some valid formulas are:
- P1+P2
- (P1+P2)/(P4-100)
- sin(P3)/cos(P4)
The valid mathematical operators are addition,
subtraction, multiplication and division, as well as the
functions listed in the table below.
| Function |
Explanation |
| SQR |
Square function which can
be used as SQR(X) |
| SIN |
Sine function which can
be used as SIN(X). Sin returns the sine of the angle
X in radians. |
| COS |
Cosine function which can
be used as COS(X). COS returns the cosine of the angle
X in radians |
| ATAN |
ArcTangent function which
can be used as ATAN(X) |
| SINH |
Hyperbolic Sine function
which can be used as SINH(X) |
| COSH |
Hyperbolic Cosine function
which can be used as COSH(X) |
| COTAN |
Cotangent (1/tangent) which
can be used as COTAN(X) |
| TAN |
Tangent which can be used
as TAN(X) |
| EXP |
e raised to the power X
which can be used as EXP(X) |
| LN |
Natural log, which can
be used as LN(X) |
| LOG |
10 based log, which can
be used as LOG(X) |
| SQRT |
Square Root which can be
used as SQRT(X) |
| ABS |
absolute value, which can
be used as ABS(X) |
| TRUNC |
Discards the fractional
part of a number. e.g. TRUNC(-3.2) is -3, TRUNC(3.2)
is 3. |
| CEIL |
Rounds a non integer value
to the nearest integer that has a value greater than
it. i.e. CEIL(-3.2) = 3, CEIL(3.2) = 4 |
| FLOOR |
Rounds a non integer value
to the nearest integer that has a value less than it.
ie. FLOOR(-3.2) = -4, FLOOR(3.2) = 3 |
| RND |
Can be used as RND(X).
Generates a random INTEGER number such that 0 <=
Result < X. |
| INTPOW |
Can be used as INTPOW(base,exponent).
The INTPOW function raises Base to an integral power.
INTPOW(2, 3) = 8. Note that result of INTPOW(2, 3.4)
= 8 as well |
| POW |
Can be used as POW (base,exponent).
The Power function raises Base to any power. For fractional
exponents or exponents greater than MaxInt, Base must
be greater than 0. |
| MIN |
Can be used
as MIN(A,B). Returns the value of A or B, whichever
is smaller. |
| MAX |
Can be used as MAX(A,B).
Returns the value of A or B, whichever is larger. |
