An error caused by truncating the trailing digits of a figure or number.

An error caused by truncating the trailing digits of a figure or number.

• A. Truncation error
• B. Logical error
• C. Arithmetic error
• D. Semantic error

Answer: (A)

Truncation error happens when you drop trailing digits to fit a chosen precision, so the value stored is not the exact one. This loss of precision means the result differs from the true value because those discarded digits can affect the overall accuracy. For example, truncating 12.345 to 12.34 leaves an error of 0.005. This type of error is about how numbers are represented or stored, not about whether the algorithm is logically correct or whether a calculation was performed correctly. Logical errors come from wrong steps in an algorithm, arithmetic errors from miscalculations, and semantic errors from a mismatch between meaning and implementation. Truncation error is specifically the precision loss from discarding digits.
