Function Val(value as String) as numeric value

[edit] Description

Val attempts to extract a number literal from the passed string and convert it to a number. If it fails, it returns 0.

[edit] Discussion

Val looks for a numeric literal from the beginning of the string, Thus it will read a string like "123abc" and return the value 123.

Val recognizes the literal prefixes &b, &o, &h, and will consider them when parsing the numeric data.

[edit] Sample Code

dim pi as Double = Val(3.1415927)

dim fortySeven as Integer = Val("&b00101111")
