NightPortion method returns 0 for angle based rule calculations

[nadsmoo]

Asalamu alaikum wa rahmatullahi wa barakatu akhi,

The line :
if (this.HighLatitudeAdjustmentMethod == HighLatitudeAdjustmentMethods.AngleBased)
return 1 / 60 * angle;

Should be :
if (this.HighLatitudeAdjustmentMethod == HighLatitudeAdjustmentMethods.AngleBased)
return 1d / 60d * angle;

Without this, the fraction returns 0 ( as it does integer division and returns a whole number), by setting the values to doubles a fraction is returned and angle based calculations work correctly.

Jazakallahu khairan for your good work.
