New operator:
• The new \'~=\' operator checks for the approximate equality of objects, using Donald Knuth\'s numerical method. The operator is very useful to cope with round-off errors in floating point operations. To change the epsilon threshold, please use the environ.kernel/eps facility, changing the value of the global system variable `Eps` will not work due to performance and consistency reasons, e.g.: environ.kernel(\'eps\':1e5);
To check the current setting of the \'~=\' epsilon setting, just enter:
• environ.kernel(\'eps\')
Miscellaneous:
• `calc.fsum` has been extended to also process multivariate functions.
• The new C API function `agn_getepsilon` returns the setting of the accuracy threshold epsilon used by the \'~=\' operator and the `approx` function. `agn_setepsilon` sets the threshold.
Improvement of the `linalg` package:
• The new function `trace\' determines the trace of a square matrix using Kahan-Ozawa summation to prevent (or at least minimize) roundoff errors.
• The new functi...
