OpenLcbFloat16_get_direction
bool OpenLcbFloat16_get_direction(uint16_t half)
Returns true if the direction bit is set (reverse).
Definition openlcb_float16.c:281

OpenLcbFloat16_negate
uint16_t OpenLcbFloat16_negate(uint16_t half)
Flips the sign/direction bit of a float16 value and returns the result.
Definition openlcb_float16.c:217

OpenLcbFloat16_from_float
uint16_t OpenLcbFloat16_from_float(float value)
Converts a 32-bit float to a float16 bit pattern.
Definition openlcb_float16.c:83

OpenLcbFloat16_to_float
float OpenLcbFloat16_to_float(uint16_t half)
Converts a float16 bit pattern to a 32-bit float.
Definition openlcb_float16.c:163

OpenLcbFloat16_get_speed
float OpenLcbFloat16_get_speed(uint16_t half)
Returns the speed magnitude from a float16 bit pattern (ignores direction).
Definition openlcb_float16.c:270

OpenLcbFloat16_is_nan
bool OpenLcbFloat16_is_nan(uint16_t half)
Returns true if the float16 bit pattern represents NaN (speed not available).
Definition openlcb_float16.c:225

OpenLcbFloat16_is_zero
bool OpenLcbFloat16_is_zero(uint16_t half)
Returns true if the float16 bit pattern represents positive or negative zero.
Definition openlcb_float16.c:236

OpenLcbFloat16_speed_with_direction
uint16_t OpenLcbFloat16_speed_with_direction(float speed, bool reverse)
Encodes a speed magnitude and direction into a float16 bit pattern.
Definition openlcb_float16.c:244
