pow function

dynamic pow(dynamic x, dynamic exponent)

Raises a number to the power of another number.

Example 1:

print(pow(2, 3));  // Output: 8.0

Example 2:

var xxx = Complex(1, 2);
print(pow(2, xxx));  // Output: 0.36691394948660344 + 1.9660554808224875i

Implementation

dynamic pow(dynamic x, dynamic exponent) {
  if (x is Expression || exponent is Expression) {
    final base = x is Expression ? x : Literal(x);
    final exp = exponent is Expression ? exponent : Literal(exponent);
    return Pow(base, exp);
  }
  if (x is num || x is Complex) return Complex(x).pow(exponent);
  if (x is Matrix) return MatrixFunctions(x).pow(exponent);
  throw ArgumentError('Input should be num, Complex, Matrix, or Expression');
}
