Examples of ptolemy.data.DoubleToken

ptolemy.data.DoubleToken
A token that contains a 64-bit signed mantissa, signed exponent double precision floating-point number (IEEE 754). This class handles overflow and underflow as does normal java arithmetic on doubles.
Note that a double cannot be losslessly converted to a long, and vice versa, as both have 64-bit representations in Java. @see ptolemy.data.Token @author Neil Smyth, Yuhong Xiong, Christopher Hylands, Steve Neuendorffer @version $Id: DoubleToken.java,v 1.140 2007/12/07 06:31:40 cxh Exp $ @since Ptolemy II 0.2 @Pt.ProposedRating Yellow (cxh) nil token, ONE, ZERO @Pt.AcceptedRating Red (cxh)
