Base64Decode
Base64Decode (inputStr)
The Base64Decode function returns a decoded copy of the Base64-encoded string inputStr. The contents of inputStr are not checked for validity. Any invalid characters in inputStr are skipped, and decoding continues with subsequent characters.
The algorithm used to encode Base64-encoded data is defined in RFC 4648 (http://www.ietf.org/rfc/rfc4648.txt).
For an explanation of Base64 encoding, see https://en.wikipedia.org/wiki/Base64.
The Base64Decode function was added in Igor Pro 8.00.
Example
String encodedString = "SWdvciBpcyBncmVhdCE="
Print Base64Decode(encodedString)
Igor is great!
