The numfromstr parses the head of the string for a number, accepting optional signs. The code has been prepared to continue parsing by returning the number of characters read. In the M5/M4 it is ignored. In Pf code base this return value is compaired to <=0. SQL will use it.

Two errors are possible. It does not represent a number (return 0)
or there is an overflow (silently ignored).
