*GOLDENANGLE() displays the golden angle in degrees if the argument is TRUE (or 1) and in radians if the argument is FALSE (or 0).
*GOLDENANGLE() displays the golden angle in degrees if the argument is TRUE (or 1) and in radians if the argument is FALSE (or 0).
*If 'a' and 'b' are two arcs where 'a' is longer arc and 'b' is smaller arc, then Golden angle is the angle subtended by the smaller arc when two arcs make a circle in golden ratio.
*If 'a' and 'b' are two arcs where 'a' is longer arc and 'b' is smaller arc, then Golden angle is the angle subtended by the smaller arc when two arcs make a circle in golden ratio (φ).
It is represented as -
It is represented as -
Golden Angle = <math>\frac{a+b}{a}</math> = <math>\frac{a}{b}</math> = <math>360(2-φ)</math>
Golden Angle = <math>\frac{a+b}{a}</math> = <math>\frac{a}{b}</math> = <math>360(2-φ)</math>
*The value of golden ratio is approximately ''137.508°'' or ''2.399963 radians''.
*The value of Golden Angle is approximately ''137.508°'' or ''2.399963 radians''.
*Argument <math>isdegrees</math> can be logical values TRUE (or 1) or FALSE (or 0). Any other argument values are ignored and Calci assumes it to be TRUE or 1.
*Argument <math>isdegrees</math> can be logical values TRUE (or 1) or FALSE (or 0). Any other argument values are ignored and Calci assumes it to be TRUE or 1.
*If argument <math>isdegrees</math> is omitted, Calci assumes it as TRUE or 1 and displays the golden angle in degrees.
*If argument <math>isdegrees</math> is omitted, Calci assumes it as TRUE or 1 and displays the golden angle in degrees.
