Yeah, but the problem isn’t on ‘nix, it’s on Windows and specifically in 
PowerShell.

Although I have never looked at this shell language before, I suspect "complete". Going to the formal language definition, it clearly makes provision for conversion of numbers expressed as strings into numeric value:


   6.16 Conversion from string to numeric type

Depending on its contents, a string can be converted explicitly or implicitly to a numeric value. Specifically,

 * An empty string is converted to the value zero.
 * Leading and trailing spaces are ignored; however, a string may not
   consist of spaces only.
 * A string containing only white space and/or line terminators is
   converted to the value zero.
 * One leading + or - sign is permitted.
 * An integer number may have a hexadecimal prefix (0x or 0X).
 * An optionally signed exponent is permitted.
 * Type suffixes and multipliers are not permitted.
 * The case-distinct strings "-Infinity", "Infinity", and "NaN" are
   recognized as the values -∞, +∞, and NaN, respectively.

You can see how little time it took me to find this. (first find the formal definition of the language, then this section)
