Defined in header <complex>
template< class T > complex<T> polar( const T& r, const T& theta = 0 );

Returns a complex number with magnitude r and phase angle theta.

The behavior is undefined if r is negative or NaN, or if theta is infinite

(since C++17)

Parameters

r	-	magnitude
theta	-	phase angle

Return value

a complex number determined by r and theta
