GOLDENRATIO(phismall)

  • where is the logical value TRUE or FALSE.

GOLDENRATIO() returns the golden ratio value.

Description

  • Two quantities are in the golden ratio if their ratio is the same as the ratio of their sum to the larger of the two quantities.
  • Golden ratio is represented as phi(φ also called smallphi) and its conjugate is represented as Phi (Φ also called capitalphi).
  • If 'a' and 'b' are two quantities with 'a>b', then
φ =  = 
  • Using quadratic formula, golden ratio is represented as -
φ = Failed to parse (syntax error): {\displaystyle \frac{(1 + √5)}{2}}
 = 1.618033988749895 
Φ = Failed to parse (syntax error): {\displaystyle \frac{(1 - √5)}{2}}
 = -0.6180339887498948 (Absolute value 0.6180339887498948 is considered as capitalphi.
  • 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 output as 0.6180339887498948.
  • If argument is invalid, Calci returns a #NULL error message.

Examples

GOLDENRATIO(TRUE) returns 0.6180339887498948, value of capitalphi Φ

GOLDENRATIO(1) returns 0.6180339887498948, value of capitalphi Φ

GOLDENRATIO(FALSE) returns 1.618033988749895, value of smallphi φ

GOLDENRATIO() returns 0.6180339887498948, value of capitalphi Φ
