Agena

2.16.12, January 06, 2020 - The new function `math.uexponent` returns the unbiased exponent of number x, i.e. returns math.exponent(x) - 1, except for x = 0, where the result is -1023. - `math.fibinv` has been ported to C and has become twice as fast. - `bytes.getunbiased` has now been patched in C. The slower 2.16.11 Update 2 patch written in Agena has been removed. - Various functions of the `bytes` package no longer check whether their arguments are in range and thus do not issue any errors any longer. Thus, the stricgt changes introduced with the previous release have been completely rolled back. - Use the new `bytes.isint32` function to check whether an integer is the 4-byte integer range. It returns `true` or `false`. - Since Agena 2.16.5, `strings.find`, `strings.match`, `strings.isabbrev`, `strings.isending`, `strings.hits`, `strings.chomp`, `strings.gseparate` and `strings.advance` did not work efficiently with haystack strings of size 3 or less in case pattern matching was not necessary. The results, however, were correct. Also, on rare systems that do not store strings aligned along the 4 or 8 byte word boundary, the functions may have never returned or even crashed. Both issues have now been fixed. - The `replace` operator has become ten percent faster. - Many string search functions and operators have been tuned a little bit. - The previously undocumented C API function `agn_stralloc` efficiently creates a string buffer of optimal size, aligned along the "long" boundary, and also automatically includes a terminating zeros. - Removed undocumented Agena test functions written in C.
