x = 123.01247
print("Original  Number: ",x)
print(roundup(x, 0))
print(roundup(x, 1))
print(roundup(x, 2))
print(roundup(x, 3))
```
```

r"(\s|_|-)+","-",
sub(
r"[A-Z]{2,}(?=[A-Z][a-z]+[0-9]*|\b)|[A-Z]?[a-z]+[0-9]*|[A-Z]|[0-9]+",
lambda mo: mo.group(0).lower(), s))

print(tips_kebab('sentenceCase'))
print(tips_kebab('Python Tutorial'))
print(tips_kebab('the-quick_brown Fox jumps_over-the-lazy Dog'))
print(tips_kebab('hello-world'))
```

Output:

```sentencecase
