Unformatted text preview: VALUES Numerical values must be correct. Errors by the design engineer create errors in all subsequent design, construction and contract evaluations. PRECISION Precision in numerical values indicates a requirement for exactness in dimensions, material properties and structural capacities. Precision for computations in CVEN 4545 is three significant digits. Round the third digit. Numerical values are wrong if precision is wrong. Some examples: Computation Result at 3-digit precision 123,456.789 123,000 123.456789 123 12.3456789 12.3 0.123456789 0.123 UNITS In engineering, numerical values almost always have units. All values that require units may be misunderstood if units are not reported. Numerical values are wrong if the units are missing. Numerical values are wrong if the units are wrong. ...
