VBS Convert String to Double: Understanding VBScript's Data Type Conversions

VBScript, a powerful scripting language developed by Microsoft, offers various functions that can coerce an expression to a specific data type. In this article, we will delve into the world of VBS convert string to double and explore how these functions work.

Data Type Conversions in VBScript

When it comes to data type conversions, VBScript provides several built-in functions that can help you achieve your goals. These functions are compiled inline, meaning they are part of the code that evaluates the expression. This approach improves performance by eliminating the need for a separate call to a procedure.

VBS Convert String to Double: The Function That Converts

The `Cdbl` function is one such conversion function provided by VBScript. It converts an expression to a double data type, which means it can handle values up to 1.79x10^308. This function is useful when you need to perform calculations that require precise floating-point arithmetic.

Example: Converting a String to Double

To demonstrate the usage of `Cdbl`, let's consider an example. Suppose you have a string variable `myString` containing the value '123.45'. You can convert this string to a double data type using the following code:

```vb

Dim myString As String

myString = '123.45'

myDouble = Cdbl(myString)

```

In this example, the `Cdbl` function converts the string variable `myString` to a double data type and stores it in the `myDouble` variable.

In conclusion, VBScript's data type conversion functions provide an efficient way to coerce expressions to specific data types. The `Cdbl` function, in particular, is useful when you need to convert strings to double data types for precise floating-point calculations. By understanding these functions and how they work, you can write more effective and efficient scripts using VBScript.
