In the case you are using redlib, you have to remove "CR_INTEGER_PRINTF" define from project settings -> Compiler -> Preprocessor.

The effect should be like this:

float x = 123.456;

printf("++++++++++++++++\n");

printf("%6.2f\n", x);

printf("%9.2f\n", x);

printf("%12.2f\n", x);

printf("%-6.2f\n", x);

printf("%-9.2f\n", x);

printf("%-12.2f\n", x);

Output:

++++++++++++++++

123.46

More details on CR_INTEGER_PRINTF can be found on MCUXpresso_IDE_User_Guide.pdf, chapter "16.5.1 Redlib printf Variants", paragraph: "Integer only vs full printf (including floating point)"

The symbol #PRINTF_ADVANCED_ENABLE needs to be set. That adds support in.
