function template

std::polar

template<class T> complex<T> polar (const T& rho, const T& theta = 0);

Complex from polar components

Returns a complex object (in cartesian format) corresponding to the complex number defined by its polar components rho and theta, where rho is the magnitude (modulus) and theta is the phase angle. The values in the return value are the same as if:

1
2

real = rho * cos(theta);
imag = rho * sin(theta);

Parameters

rho: Magnitude (modulus) of the complex number.
theta: Phase angle (angular component) of the complex number.

T is the type of the components of the complex type (i.e., its value type).

Return value The complex cartesian equivalent to the polar format formed by rho and theta.

Example

// polar example
#include <iostream>     // std::cout
#include <complex>      // std::complex, std::polar

int main ()
{
  std::cout << "The complex whose magnitude is " << 2.0;
  std::cout << " and phase angle is " << 0.5;
  std::cout << " is " << std::polar (2.0, 0.5) << '\n';

  return 0;
}

Output:

The complex whose magnitude is 2 and phase angle is 0.5 is (1.75517,0.958851)
