Powers and roots

The MQL5 API provides a generic function MathPow for raising a number to an arbitrary power, as well as a function for a special case with a power of 0.5, more familiar to us as the operation of extracting a square root MathSqrt.

To test the functions, use the MathPowSqrt.mq5 script.

double MathPow(double base, double exponent) ≡ double pow(double base, double exponent)

The function raises the base to the specified power exponent.

double MathSqrt(double value) ≡ double sqrt(double value)

The function returns the square root of a number.

MQL5 defines several constants containing ready-made calculation values involving sqrt.

Here M_PI is the Pi number (π=3.14159265358979323846, see further along the section Trigonometric functions).

All built-in constants are described in the documentation.
