例如在「石膏板用量」中填 墙总长 m = 16，墙高 m = 2.6，门窗面积 m² = 4，板宽 m = 1.2，板高 m = 2.4，损耗 % = 10，结果区显示：净面积：37.6 m²；石膏板张数：15For example, entering Total wall length m = 16, Wall height m = 2.6, Openings m² = 4, Sheet width m = 1.2, Sheet height m = 2.4, Waste % = 10 in the Drywall Calculator gives: Net area: 37.6 m²; Sheets: 15

哪些输入会被检查？Which inputs are validated?

「石膏板用量」会检查这些输入——「墙总长 m」、「墙高 m」、「板宽 m」、「板高 m」：必须填写，须大于 0；「门窗面积 m²」、「损耗 %」：必须填写，不能为负数；绝对值超过 10¹⁵ 的数也会被拒绝。不符合时结果区显示具体提示，不会给出数字。The Drywall Calculator checks its inputs — "Total wall length m", "Wall height m", "Sheet width m", "Sheet height m": required, must be greater than 0; "Openings m²", "Waste %": required, cannot be negative; numbers above 10¹⁵ in absolute value are rejected too. When a value fails, the result area names the problem instead of showing a number.

有哪些选项可以调整？What options can I adjust?
