# --description--
|
|
|
|
Given two numbers, determine if their ratio approximates the golden ratio.
|
|
|
|
- Use a golden ratio of `1.618`
|
|
- Allow a tolerance of `0.01`
|
|
|
|
# --hints--
|
|
|
|
`is_golden_ratio(21, 34)` should return `True`.
|
|
|
|
```js
|
|
({test: () => { runPython(`
|
|
from unittest import TestCase
|
|
TestCase().assertIs(is_golden_ratio(21, 34), True)`)
|
|
}})
|
|
```
|
|
|
|
`is_golden_ratio(15, 20)` should return `False`.
|
|
|
|
```js
|
|
({test: () => { runPython(`
|
|
from unittest import TestCase
|
|
TestCase().assertIs(is_golden_ratio(15, 20), False)`)
|
|
}})
|
|
```
|
|
|
|
`is_golden_ratio(8, 13)` should return `True`.
|
|
|
|
```js
|
|
({test: () => { runPython(`
|
|
from unittest import TestCase
|
|
TestCase().assertIs(is_golden_ratio(8, 13), True)`)
|
|
}})
|
|
```
|
|
|
|
`is_golden_ratio(10, 16)` should return `False`.
|
|
|
|
```js
|
|
({test: () => { runPython(`
|
|
from unittest import TestCase
|
|
TestCase().assertIs(is_golden_ratio(10, 16), False)`)
|
|
}})
|
|
```
|
|
|
|
`is_golden_ratio(1618, 1000)` should return `True`.
|
|
|
|
```js
|
|
({test: () => { runPython(`
|
|
from unittest import TestCase
|
|
TestCase().assertIs(is_golden_ratio(1618, 1000), True)`)
|
|
}})
|
|
```
|
|
|
|
`is_golden_ratio(88, 55)` should return `False`.
|
|
|
|
```js
|
|
({test: () => { runPython(`
|
|
from unittest import TestCase
|
|
TestCase().assertIs(is_golden_ratio(88, 55), False)`)
