Sinc (FPScript)
Calculates the sinc function Sin(Angle)/Angle.
Syntax
Sinc(Angle)
The syntax of the Sinc function consists of the following parts:
Part |
Description |
---|---|
Angle |
The angle in radians. All data structures are allowed. All numeric data types are permitted. |
Remarks
The data type of the result is always 64-bit floating point.
The structure of the result corresponds to that of the argument Angle. The calculation is done element-by-element where appropriate.
The result has the unit 1, if Angle has a unit. Otherwise, it has no unit.
For aggregate data structures, only the Y component is calculated.
The function is defined as 1 for x = 0 and Sin(x) / x for all x ≠ 0.
The following illustration shows the course of the function within the interval [-8π, 8π]:
If the argument is a list, then the function is executed for each element of the list and the result is also a list.
For complex data types the absolute value is formed.
