Class ExprValue

java.lang.Object
  tcl.lang.ExprValue

public final class ExprValue
extends Object

Describes an expression value, which can be either an integer (the usual case), a double-precision floating-point value, or a string. A number type will typically have a string value that is the number string before it was parsed into a number. If the number has no string value then one will be generated by getStringValue().
