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) and its conjugate is represented as Phi (&Phi).
- If 'a' and 'b' are two quantities with 'a>b', then
(φ) = Failed to parse (syntax error): {\displaystyle \frac{\(a + b)}{a}} = Failed to parse (unknown function "\a"): {\displaystyle \frac{\a}{b}}
- Using quadratic formula, golden ratio is represented as -
φ = Failed to parse (syntax error): {\displaystyle \frac{1+&sqrt; 5}{2}} = 1.618033988749895
Φ = Failed to parse (syntax error): {\displaystyle \frac{1-&sqrt; 5}{2}} = 0.6180339887498948
- 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
