Question 19

The subroutine CheckAcceleration is used in a self-driving vehicle's stability control system. The variable lateral_accel represents the lateral acceleration in $m/s2\text{m/s}^2$ and can store values such as $- 2.5$ , $0.0$ , or $1.85$ .

SUBROUTINE CheckAcceleration(lateral_accel)
  IF lateral_accel < -1.5 OR lateral_accel > 1.5 THEN
    RETURN 'W'
  ELSE
    RETURN 'S'
  ENDIF
ENDSUBROUTINE

State the most appropriate data type for each of these sets of values.

Values	Data type
$- 2.5, 0.0, 1.85$
`'W', 'S'`
