Macro Definition Documentation

FLT_FMT

#define FLT_FMT

(

_n

)

Value:

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

)

Value:

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 )

Value:

PPCAT_NX(A, B)

concatenate tokens

PPCAT_NX

#define PPCAT_NX	(		A,
			B )

Value:

A##B

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

STRINGIZE

#define STRINGIZE

(

A

)

Value:

STRINGIZE_NX(A)

make a string

STRINGIZE_NX

#define STRINGIZE_NX

(

A

)

Value:

#A

non-expanding stringize
