Is there a syntax to cast from one character type for another? For example can you cast from a char to an int?

I tried:

let my_var = (int)some_char

It is not valid code.

    It helps reading Vim's scripting help first ... To quote: Vim automatically converts a string to a number when it is looking for a number. If you want ASCII char conversion instead, see char2nr() and nr2char().

    And there's the str2nr function.

    If you know it is a number, you can also simply add zero to it.

The answer is no. There is no general syntax to cast from one type to another. There are unique ways of converting to different types, but no universal casting syntax.

You can do this in a round about way by first casting the float to a string then casting it to number for example:

echom str2nr(string(log10(200)))

Hope this helps people searching in the future.
