float hypot_f	(	float	x,
		float	y
	)

Simple hypotenuse computation function.

Computes hypotenuse, avoiding avr-gcc's bloated version and the extra error checking.

float limit_value_by_axis_maximum	(	float *	max_value,
		float *	unit_vec
	)

< Avoid divide by zero.

uint8_t read_float	(	char *	line,
		uint8_t *	char_counter,
		float *	float_ptr
	)

Extracts a floating point value from a string. The following code is based loosely on.

Read a floating point value from a string. Line points to the input buffer, char_counter.

NOTE: Thanks to Radu-Eosif Mihailescu for identifying the issues with using strtod().

< intval*10 + c

< Set char_counter to next statement
