MathML test: Formula by Ramanujan

A remarkable formula by Srinivasa Ramanujan

$\sqrt{\frac{π}{2} \frac{e^{x}}{x}} = \frac{1}{x + \frac{1}{1 + \frac{2}{x + \frac{3}{1 + \frac{4}{x + \frac{5}{1 + \frac{6}{x + \frac{7}{⋱}}}}}}}} + {1 + \frac{x}{1 \cdot 3} + \frac{x^{2}}{1 \cdot 3 \cdot 5} + \frac{x^{3}}{1 \cdot 3 \cdot 5 \cdot 7} + \dots}, x > 0$
