Our string consists of the four character values 2, 5, 7 & 8: x # Print example vector to R console . 'false' evalutes to FALSE, because it evaluates if the string 'false' exists and negates the valueNormally I would just ignore this post but it is well ranked on Google for me so I will post a correction for the sake of others who come here. ToBoolean(String, IFormatProvider) Converts the specified string representation of a logical value to its Boolean equivalent, using the specified culture-specific formatting information. The Data Type of typeof. You say:The right implementation that would work no matter if you initialize your variable with the Boolean true|false or with the String true|false would be:var myString=X; // where X could be any “true”|”false”|true|false!
Otherwise, it must be false. We can do it this way:Wonderful, it looks like our problem is solved! As you can see in the above example, a valid numeric string can be converted to an integer. Because myString is Really, the correct way we should be going about this is to check if our string equals “true” — if so, then our string is obviously “true”.

The typeofoperator is not a variable.It is an operator. Thanks again and good luck.
