The _PI function returns π as a _FLOAT value with an optional multiplier parameter.
Syntax
- circumference = _PI[(multiplier)]
Parameters
- Optional multiplier (2 * radius in above syntax) allows multiplication of the π value.
Description
- Function can be used in to supply π or multiples in a program.
- Accuracy is determined by the return variable type AS SINGLE, DOUBLE or _FLOAT.
- The π value can also be derived using 4 * ATN(1) for a SINGLE value.
Examples
Example: Calculating the area of a circle using a SINGLE variable in this case.
radius = 5 circlearea = _PI(radius ^ 2) PRINT circlearea |
78.53982 |
