* Fixed to truncate as "1.234M" instead of "1234K" * Optimized by switching to strings to avoid divisions * Changed FP constants to strings --------- Co-authored-by: Copilot <175728472+Copilot@users.noreply.github.com>

* @brief A set of macros to map the fonts decimal-point values (e.g. ".1")
|
|
* to their replaced characters.
|
|
*
|
|
* "FP#" -> Font "Point" "number"
|
|
*
|
|
*
|
|
* For example:
|
|
* ```c
|
|
* tte_printf("Testing " FP0_STR " Something!");
|
|
* ```
|
|
* prints "Testing .0 Something!"
|
|
*
|
|
* The map is the following:
|
|
*
|
|
* ```c
|
|
* '&' == '.0'
|
|
* '^' == '.1'
|
|
* '}' == '.2'
|
|
* '{' == '.3'
|
|
* '|' == '.4'
|
|
* '`' == '.5'
|
|
* '<' == '.6'
|
|
* '>' == '.7'
|
|
* '_' == '.8'
|
|
* ';' == '.9'
