From Real Software Documentation
Method
Returns the numeric form of a string as an Int64.
Syntax
result=CLong(string)
OR
Introduced 5.0 result=stringVariable.CLong
| Part | Type | Description |
|---|---|---|
| result | Int64 | The numeric equivalent of the string passed. |
| string | String | Any valid string expression. |
| stringVariable | String | Any variable of type String. |
Notes
The CLong function stops reading the string at the first character it doesn’t recognize as part of a number. All other characters are automatically stripped.
It does recognize prefixes &o (octal), &b (binary), and &h (hexadecimal). However, spaces are not allowed in front of the ampersand. That is, " &hFF" returns 0, but "&hFF" returns 255.
CLong returns zero if string contains no numbers.
Examples
These examples use the CLong function to return the numbers contained in a string literal or a string variable
Dim n As Int64
Dim s As String
n = CLong("12345") //returns 12345
n = CLong(" 12345") //returns 0
n = CLong("123 45") //returns 123
n = CLong("&hFFF") //returns 4095
n = CLong("&b1111") //returns 15
s="12345"
n=s.CLong //returns 12345
Dim s As String
n = CLong("12345") //returns 12345
n = CLong(" 12345") //returns 0
n = CLong("123 45") //returns 123
n = CLong("&hFFF") //returns 4095
n = CLong("&b1111") //returns 15
s="12345"
n=s.CLong //returns 12345
