A parametric function is a sequence of operations that return a single value, such as SQRT(x), LN(x), or SIN(x). The available functions for the DesignModeler application are listed in the table below.
| ABS(x) | Absolute value of x. |
| EXP(x) | Exponential of x (ex). |
| LN(x) | Natural log of x. |
| SQRT(x) | Square root of x. |
SIN(x) COS(x) TAN(x) | Sine, Cosine, and Tangent of x in degrees. |
ASIN(x) ACOS(x) ATAN(x) | Arcsine, Arccosine, and Arctangent of x. x must be between -1.0 and +1.0 for ASIN and ACOS. Output is in degrees by default. Range of output is -90 to +90 for ASIN and ATAN, and 0 to 180 for ACOS. |
CEIL(x) | Ceiling of x. Rounds x up to the nearest integer. |
FLOOR(x) | Floor of x. Rounds x down to the nearest integer. |
ROUND(x) | Round of x. Rounds x to nearest integer (0.5 or greater rounds up, lower rounds down). |
MIN(x; ...) | Maximum value of a set. The input must be a non-empty, semicolon-delimited set of expressions. |
MAX(x; ...) | Minimum value of a set. The input must be a non-empty, semicolon-delimited set of expressions. |
Note: The maximum number of digits used for calculation for CEIL and FLOOR functions are 15 (this includes digits before and after decimal, if any).
Example 104: Parametric Functions
A = acos (-1) # Evaluates to 180
B = abs (x) # Evaluates to |x|
C = asin (sqrt (2) / 2)) # Evaluates to 45
D = exp(ln(x)) # Evaluates to x
E = max (floor (7.67); ceil (7.67)) # Evaluates to 8
F = min (round (6.5); round (6.4)) # Evaluates to 6
