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.

Sample code

This code 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

Compatibility
