Macro Definition Documentation

◆ FLT_FMT

#define FLT_FMT ( _n ) STRINGIZE(PPCAT(PPCAT(%c%d.%0, _n), d))

Floating point output formatting string. Include in your printf-style format string example: printf("float value = " FLT_FMT(3) " continue like that", FLT_VAR(3, x));

◆ FLT_FMT3

#define FLT_FMT3 FLT_FMT(3)

Shorthand for 10^-3 fraction, output equivalent to %.3f

◆ FLT_VAR

#define FLT_VAR	(	_n,
		_x
	)

Value:

(_x < 0 ? '-' : ' '), (int)(abs(_x)), \

(int)(((abs(_x)) - (int)(abs(_x))) * pow(10, (_n)))

Floating point output variable preprocessing Note: uses truncation instead of rounding -> the last digit may be off

◆ FLT_VAR3

#define FLT_VAR3 ( _x ) FLT_VAR(3, _x)

Shorthand for 10^-3 fraction

◆ LOGGER_BUFFER

#define LOGGER_BUFFER 128

size in bytes

◆ LOGGER_NEWLINE

#define LOGGER_NEWLINE "\r\n"

Logger configuration custom newline character sequence

◆ PPCAT

#define PPCAT	(	A,
		B
	)	PPCAT_NX(A, B)

concatenate tokens

◆ PPCAT_NX

#define PPCAT_NX	(	A,
		B
	)	A##B

Helper macros for string concatenation and macro expansion non-expanding concatenation

◆ STRINGIZE

#define STRINGIZE ( A ) STRINGIZE_NX(A)

make a string

◆ STRINGIZE_NX

#define STRINGIZE_NX ( A ) #A

non-expanding stringize
