- version>=? V1 V2procedure
Compares the version numbers V1 and V2 and returns #t if V1 is "less" than V2 or #f otherwise. A version number can be an integer, a floating-point number or a string. version>=? handles dot-separated version-indicators of the form "X.Y. ..".
If one version number is the prefix of the other, then the shorter version is considered "less" than the longer.
