public final class Value extends Fixed1ArgFunction implements ArrayFunction
Syntax:
VALUE(text)
Converts the text argument to a number. Leading and/or trailing whitespace is ignored. Currency symbols and thousands separators are stripped out. Scientific notation is also supported. If the supplied text does not convert properly the result is #VALUE! error. Blank string converts to zero.
(Excel VALUE() 函数的实现。语法:VALUE(text) 将文本参数转换为数字。忽略前导和/或尾随空格。货币符号和千位分隔符被删除。也支持科学记数法。如果提供的文本未正确转换,则结果为#VALUE!错误。空白字符串转换为零。)Constructor and Description |

args
- the evaluated function arguments. Empty values are represented with
BlankEval
or
MissingArgEval
, never
null
.
(args - 评估的函数参数。空值用 BlankEval 或 MissingArgEval 表示,绝不为 null。)
srcRowIndex
- row index of the cell containing the formula under evaluation
(srcRowIndex - 包含计算公式的单元格的行索引)
srcColumnIndex
- column index of the cell containing the formula under evaluation
(srcColumnIndex - 包含正在评估的公式的单元格的列索引)
ErrorEval
, never
null
.
Note - Excel uses the error code
#NUM! instead of IEEE
NaN, so when numeric functions evaluate to
Double.NaN
be sure to translate the result to
ErrorEval.NUM_ERROR
.
(评估结果,可能是 ErrorEval,绝不为空。注意 - Excel 使用错误代码 #NUM!而不是 IEEE NaN,因此当数值函数计算为 Double.NaN 时,请务必将结果转换为 ErrorEval.NUM_ERROR。)

null
if there is any problem converting the text
(如果转换文本有任何问题,则返回 null)
