Note: If a floating point result is expected, at least one of the terms in the calculation
must contain a floating point value. This is true even if the terms are all hard coded.
Example:
ACCEL = 1000 (integer)
VELOCITY = 180 (integer)
Calculation:
Answer = sqrt (ACCEL/VELOCITY)
The above calculation does not produce accurate results because none of the terms are
floating points. The answer should be 2.35702, but is reported as 406.
One solution is to multiply the expression by 1.0. Another solution appears on the
following page.
Example:
ACCEL = 100.0 (floating point)
VELOCITY = 180 (integer)
Calculations:
Answer = sqrt (ACCEL/VELOCITY) or
Answer = sqrt (ACCEL/180.0) will produce the correct answer: 2.35702.
