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 |
