In this article, we will create a custom-function to convert negative strings to an integer.
Raw data for this article consists of strings followed by a minus sign (-).
We want to convert these strings to integers.
In this article, we have created a custom-function ConvertNegNumbers to convert the string to integer. This function takes string value as input and returns integer as output.
Right(Var, 1) = “-”
The above code is used to check whether last character of the string is equal to minus sign (-).
ConvertNegNumbers = CInt(“-” & Left(Var, Len(Var) – 1))
In above code, the left function is used to extract all the characters in the string, except the last one. The CInt function is used to convert string value to integer.
Please follow below for the code
Option Explicit Function ConvertNegNumbers(Var As String) 'Checking whether last character in the string is minus(-) If Right(Var, 1) = "-" Then 'Converting string value to negative integer ConvertNegNumbers = CInt("-" & Left(Var, Len(Var) - 1)) Else 'Converting string value to integer ConvertNegNumbers = CInt(Var) End If End Function
