Filters.number介绍

[英]Treat provided value as a Number, used for math opperations.

This function allows for the non stongly typed Math Opperations favoured by the Expression standard.

Able to hanle:

• null - to NaN
• Number
• String - valid Integer and Double encodings
  [中]将提供的值视为数字，用于数学运算。
  此函数允许表达式标准喜欢的非类型化数学运算。
  能够理解：
  *空对空
  *数
  *字符串-有效的整数和双编码
