Converting Strings to Numbers

There are many times when writing macros that you need to convert strings to numbers. You can do this with the Val() function. This function returns the value of a string, up to the first nonnumeric character. The following are examples:

A = Val(MyString)
B = Val("-12345.67")
C = Val("9876")
D = Val("   4     5  2      1")

The first line converts MyString into a value, placing it in A. The second line results in B being set to —12345.67. The third places the value 9876 into C, and the final line sets D equal to 4521. Notice that spaces are ignored in the conversion; this is why the final line works the way it does. You should also note that trying to use formatted numbers in a conversion will confuse the Val() function. Thus, Val("1,234") would not return a value of 1234 (as one might hope), but a value of 1. The conversion stops at the first nonnumeric character, in this case the comma.

Note:

You have a point. Here are the Visual Basic Editor's Immediate Window results for the Tip's examples:

?CDbl("-12345.67")
-12345.67

?CDbl("9876")
9876

?CDbl(" 4 5 2 1")
Run-time error '13': Type mismatch

?CDbl("1,234")
1234

CDbl is better than VAL function for converting decimals.
