FloatValue()

From ElectronicWar

[edit] Challenge Script Example

If the challenge input were an array containing the integer 33, and you had to output the area of a circle, where the radius was the input, you could use the following script:

float radius = floatValue(getInputInt())
float area = getPI()*radius*radius;
setOutputFloat(area);
}

To calculate the area of a circle you use the formula Pi * r². As Pi is expressed as a float (3.14159) it is necessary to also store the radius as a float. Giving floatValue() the radius getInputInt() will convert it to a float value.
