The first condition should be d (I mean x value in the formula) used instead of the ascendant value found

The first condition should be x < 0 (I mean d value), The x (d) value in the formula should be used instead of the ascendant value found in the first condition.

• The Ascendant is then found in the correct quadrant (0 to 360 degrees) by using the two rules https://wikimedia.org/api/rest_v1/media/math/render/svg/68649ded47b9e668ef643fbf313d157ed4037022

const b = sinFromDegrees(obliquityEcliptic) * tanFromDegrees(latitude) const c = cosFromDegrees(obliquityEcliptic) * sinFromDegrees(localSiderealTime) const d = b + c

Line if (d < 0) { ...

So, I've tried a lot and it's true that way (of course it still needs verification)

thanks a lot Onur
