The golden ratio \(\varphi = (1 + \sqrt{5})/2\), also known as golden section. This is a number such that if \(a = \varphi b\), for some non-zero \(a\) and \(b\), then it must also be true that \(a + b = \varphi a\).

The constant is stored with float64 precision, and its value is 1.618033988749895.
