温馨提示
常见错误
Avoid these frequent rounding errors when validating outputs.
- Calling truncate a nearest-value rounding method.
- Confusing truncate with floor for negatives.
- Using truncation where tie-aware rounding is required.
- Dropping expected output precision in display formatting.
❓ 常见问题解答
常见问题解答
Is truncation the same as rounding?
No. Truncation removes digits without choosing the nearest value.
How is truncate different from floor?
Truncate goes toward zero, while floor goes toward negative infinity.
When should truncation be used?
Use truncation when exact cut-off behavior is required by your process.
Can truncation be applied to large place values?
Yes. It works for tens, hundreds, thousands, and other supported places.
