![]() For this, we need to use the CDbl function. In this example, we’ll turn the input strings into double datatype (double-precision floating-point) numbers. But it’ll also get an error if the input numeric value is out of range. In the output, cells B3:B9 contain some numerical string value, and converted single datatype numbers are in cells C3:C9. Run the following code in the visual basic editor. For this, we need to use the CSng function. In this example, we’ll turn the input strings into single datatype (single-precision floating-point) numbers. Run the following code to convert the numerical values in cells B3:B7 to the decimal datatype. Using the CDec function we can convert a numerical string value to a decimal datatype. The CLng function converted -3280 successfully to long numbers which the CInt function couldn’t. Here, cells B3:B9 contain some numerical string value, and converted l ong numbers are in cells C3:C9. The CLng function converts a numeric string value to a long datatype. If we put a numeric value that is out of this range, Excel will show an error. The integer value has a range between -32,768 to 32,767. But the decimal numeric string value turns into the next integer number if it is equal to or greater than. 5, the function rounds down to the same number. When a decimal numeric value is less than. On the other hand, it converted 10.3 to 10, not 11. ![]() The CInt function converted 25.5 to the next integer number 26. We used the Cells function to specify the input values and where to print the output values. In this code, we used the For…Next loop to apply the CInt function on the strings of cells B3:B7. The output is here in the following screenshot. ![]() To understand more about the CInt function, run the following code in the code editor and observe the results. The CInt function converted the numeric string value (“12.3”) to an integer 12. Let’s try the following code in the Visual Code Editor. The CInt function takes only one argument and that should be a numeric value. To convert string to integer, we can use the CInt function in our code. We can use them in our VBA code to easily convert from string datatypes to different datatypes. Convert String to Number Using Type Conversion FunctionsĮxcel provides several built-in type conversion functions.

Here's FNV-1a in 32-bits as a single excel formula, where cell A1 has the string you want to hash: =LET( As you see there is a good comparison on the first sheet You could also just download this example workbook and play around with all 5 hash implementations. But the hash is longer and produces more collisions. There are also hash functions ( all three CRC16 functions) which doesn't require. 5 digits hash = 0 collisions in 6895 lines = 0 % collision rate. ![]() 4 digits hash = 36 collisions in 6895 lines = 0.5 % collision rate.You customize the hash length with this line: Const cutoff As Integer = 5.the hash initially is a 28 characters long unicode string (case sensitive + special chars).Set objNode = objXML.createElement("b64") Set objXML = CreateObject("MSXML2.DOMDocument") Private Function EncodeBase64(ByRef arrData() As Byte) As String SharedSecretKey = asc.GetBytes_4(sTextToHash) Public Function BASE64SHA1(ByVal sTextToHash As String) NET since it uses the library "Microsoft MSXML" (with late binding) its called with =BASE64SHA1(A1) in Excel after you copied the macro to a VBA module.You don't need to write your own function - others already did that for you.įor example I collected and compared five VBA hash functions on this stackoverflow answer
