Is there a kotlin only replacement for the java method Character.getNumericValue() ? It would be useful in kmp but i can't seem to find one.

Depends on what you need. There is Char.digitToInt but it doesn't handle roman numerals like \u216C , while Java's method does. If you only need digits in the 0-9 range (or a-z range in bases > 10), then digitToInt should be enough

digitToInt works for numbers only. the getNumericValues actually returns the full width number for A-Z which i am looking for. so A is 10 etc...

A colleague of mine wrote a blogpost about this: https://blog.jdriven.com/2019/10/converting-char-to-int-in-kotlin/

thanks. i actually found this blog post but it describes to use getNumericValues which i can not use in KMP

[Moritz Post]

for a simple solution i mapped the chars manually to the supported range in need

My apologies then 🙂 happy you found a solution!

no worries. thanks for chipping in. maybe your colleague finds a better solution for KMP as well ;)

You need to specify radix parameter > 10 to work with digits A-Z.
