tonumber() can't convert floats

[ronja-ui]

Describe the bug

If the value is a floating-point number, tonumber() returns nothing.

Expected behavior

tonumber() should be able to convert 2.5 string value to a number.

How to reproduce

| makeresults
| eval number="2.5"
| eval convert=tonumber(number)

If you try the following, it will return error instead of 2.5:

class java.lang.Double cannot be cast to class java.lang.String (java.lang.Double and java.lang.String are in module java.base of loader 'bootstrap')

| makeresults
| eval convert=tonumber(2.5)
