Shift logic may not be correct

[scuniff]

Regarding this code:

/**

• Calculate the hashCode for the data,
• The hashcode is generated by bitshifting
• z by ZTBITSPLIT bits and adding t.
• @return see above. */ public int hashCode() { int value = z<<ZTBITSPLIT+t; return value; }

=======================

I believe the shift logic

z<<ZTBITSPLIT+t

does not do what is described in the comments.

Parenthesis are needed:

(z<<ZTBITSPLIT)+t
