Agena

2.16.13, January 26, 2020 - Added the new function `math.issquare` which checks whether an integer is a perfect square. - Added the new function `math.iscube` which checks whether an integer is a perfect cube. - The new function `math.isfib` checks whether an integer is a Fibonacci number. - The new function `math.lnabs` returns ln(abs(x)) for numeric or complex x. With complex numbers, takes care of underflows. - The new `invsqrt` operator computes the inverse square root of a (complex) number. - The new `squareadd` operator computes complex z^2 + c = fma(z, z, c), preventing round-off errors. It is as fast as the Agena expression z**2 + c. - Fine-tuned internal string buffering functions used by the `replace` and `join` operators. - Fine-tuned `sin`, `cos`, `sinc`, `tan`, `log2`, `dual` package `sin` and `cos` metamethods, `root`, `proot`, `cbrt`, `cosc`, `cerf`, `gamma`, `tanc`, `cas`, `strings.shannon`, `stats.sorted`, `stats.smm`, `stats.gsmm`, `stats.prange`, `stats.iqmean`, `stats.trimean`, `stats.quartiles`, `stats.fivenum` and `stats.winsor`. - Added additional application information to the Windows installer.
