isNumber

[JVM]
fun isNumber(s: String): Boolean

This tries to quickly determine if the string is a correctly formatted number (including decimal, hexadecimal, octal, and "NaN" (any case)).

This may not be perfect. In the future, this may be changed to be perfect. That shouldn't affect its use.

Return​

true if s is probably a number. This returns false if s is definitely not a number. "NaN" (case insensitive) returns true. (It is a numeric value of sorts.) null and "" return false.

Parameters​

JVM

susually already trimmed, since any space in s will return false.
