Update History
Date Version Release notes
-------- ------- -------------
02/06/92 1.04 Complex/imaginary numbers are now fully supported.
New functions: ARG, CONJ, IMAG, NORM, and REAL for complex
numbers; FRAC to complement INT; RAND for random integers;
and SQRT for square root (SQR now gives the square of the
input value).
The INT function now gives correct values for negative
numbers.
The 'significant digits' default has been changed to 10.
The 'show variables' default has been changed to Y.
12/12/91 1.03 The 'D' option now specifies the number of significant
digits displayed, not the number of decimal places. Unless
overridden, the expression outcome will have as many decimal
places as needed (up to 20).
The trailing zeroes in decimal answers are now suppressed.
(example: 'EVAL 5/2' now defaults to '2.5', not '2.500')
09/27/91 1.02 Function errors weren't being trapped in all cases; fixed.
09/21/91 1.01 Added user-definable variables.
Multiplication is now assumed if there are no operators
between two values.
09/14/91 1.00 Initial release.
