Question
How we get the power of a number in Delphi?
Answer
This can be done with the function Power(Base,
Exponent). Because this function is in Delphi's
MATH unit, firstly you have to add MATH to the
USES statement of your unit.
Next, supposing that P is a floating point number
("real" number), you can use the function like this:
P := Power(3, 2); // 9
P := Power(2, 3); // 8
P := Power(4, 0.5); // 4 to the power 0.5
