GEOdiffAngles

Subtraction of two corners in the curve measure.

With this function the difference of both handed over corners is calculated. Besides, the second corner is drawn off from the first one and the result on the interval [-p;p] standardises.

Parametre

alpha (stands in) [IN]

beta (stands in) [IN]

Operanden of the subtraction in the curve measure. Because the result is standardised, it is uninterested which corner is the bigger one.

Result

(stands in) [OUT]

Standardised difference of both corners in the interval [-p;p].

Declaration

);

Example

delta = GEODiffAngles (0.50, 1.20)

The function delivers as a difference of the corners the value-0.7 back.

delta = GEODiffAngles (1.10, 4.75)

The function delivers as a difference of the corners the value 2.633... (-3.65+2*p) back.
