GOLDENANGLE(isdegrees)

  • where is the logical value TRUE or FALSE.

GOLDENANGLE() returns the golden angle value in degrees or radians.

Description

  • 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.

It is represented as -

Golden Angle = = = Failed to parse (MathML with SVG or PNG fallback (recommended for modern browsers and accessibility tools): Invalid response ("Math extension cannot connect to Restbase.") from server "https://wikimedia.org/api/rest_v1/":): {\displaystyle 360(2-&phi;)}

  • The value of golden ratio is approximately 137.508° or 2.399963 radians.
  • Argument 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 is omitted, Calci assumes it as TRUE or 1 and displays the golden angle in degrees.
  • If argument is invalid, Calci returns a #NULL error message.

Examples

GOLDENANGLE(TRUE) returns 137.5077508875556

GOLDENANGLE(1) returns 137.5077508875556

GOLDENANGLE(FALSE) returns 2.399963

GOLDENANGLE() returns 2.399963
