Seed7 Release 2019-06-10

Show all headers | View raw

Hello,

I have released a new version of Seed7: seed7_05_20190610.tgz
The download is here: https://sourceforge.net/projects/seed7/files
In the Seed7 programming language new statements and operators can
be declared easily. Types are first class objects and therefore
templates/generics need no special syntax. Object orientation is used
when it brings advantages and not in places when other solutions are
more obvious.

Seed7 is covered by the GPL (and LGPL for the Seed7 runtime library).

Changelog:
- The library float.s7i has been improved to support the float
  operators 'rem' (floating-point remainder) and 'mod' (floating-point
  modulo).
- The program chkflt.sd7 has been improved to check floating-point
  literals and the new operators 'rem' and 'mod'. The tests for the
  operator ** have been improved also.
- Compiler and interpreter have been improved to work correct, even
  when the C functions fmod(), exp(), ldexp(), frexp() and sqrt() do
  not work 100% correct.
- The program chkccomp.c has been improved to detect weaknesses of
  numeric functions. These weaknesses happen when handling with NaN,
  Infinity or when other special cases occur.
- A new version of the function timAwait() has been added to tim_unx.c.
  This function is used when AWAIT_WITH_NANOSLEEP is defined.
- The makefiles mk_emccl.mak and mk_emccw.mak have been improved to
  define AWAIT_WITH_NANOSLEEP instead of AWAIT_WITH_SELECT.
- Interpreter and compiler have been improved to support the actions
  FLT_MOD and FLT_REM.
- In the compiler (in comp/flt_act.s7i) a corner case of the action
  FLT_IPOW (when CHECK_FLOAT_DIV_BY_ZERO is TRUE and the exponent is
  negative and the base is zero (0.0 or -0.0)) has been fixed.
- The configuration values FLOAT_COMPARISON_OKAY, FMOD_FUNCTION_OKAY,
  EXP_FUNCTION_OKAY, LDEXP_FUNCTION_OKAY and FREXP_FUNCTION_OKAY have
  been added to cc_conf.s7i. The configuration values
  NAN_COMPARISON_OKAY and FREXP_INFINITY_NAN_OKAY have been removed.
- The functions fltDecompose(), fltExp(), fltLdexp(), fltMod() and
  fltRem() have been added to flt_rtl.c. These functions are used, when
  the corresponding C functions frexp(), exp(), ldexp() and fmod() do
  not work 100% correct.
- In flt_rtl.c the functions fltEq(), fltGe(), fltGt(), fltLe() and
  fltLt() have been improved. These improvements help, when the
  comparison of float or double values does not work 100% correct.
- In flt_rtl.c the functions fltPow(), getMantissaAndExponent(),
  setMantissaAndExponent() and fltSqrt() have been improved. These
  improvements help, when the underlying C functions pow(), frexp(),
  ldexp() and sqrt() do not work 100% correct.
- The program chkccomp.c has been improved to define the macros
  FLOAT_NAN_COMPARISON_OKAY, FLOAT_ZERO_COMPARISON_OKAY,
  SQRT_OF_NAN_OKAY, SQRT_OF_NEGATIVE_OKAY, EXP_OF_NAN_OKAY,
  LDEXP_OF_NAN_OKAY, FREXP_SUBNORMAL_OKAY, FMOD_DIVIDEND_NAN_OKAY,
  FMOD_DIVISOR_NAN_OKAY, FMOD_DIVIDEND_INFINITY_OKAY,
  FMOD_DIVISOR_INFINITY_OKAY and FMOD_DIVISOR_ZERO_OKAY.
- In cmd_rtl.c the function cmdConfigValue has been improved to support
  the config values FLOAT_COMPARISON_OKAY, EXP_FUNCTION_OKAY,
  FMOD_FUNCTION_OKAY, LDEXP_FUNCTION_OKAY and FREXP_FUNCTION_OKAY.
- Definitions of the macros FLOAT_COMPARISON_OKAY, SQRT_FUNCTION_OKAY,
  EXP_FUNCTION_OKAY, LDEXP_FUNCTION_OKAY, FREXP_FUNCTION_OKAY and
  FMOD_FUNCTION_OKAY have been added to commpn.h
- Documentation comments have been improved in intlib.c, int_rtl.c,
  match.c, str_rtl.c, keybd.s7i and vectorfont.s7i.
- In comp/int_act.s7i the variable quotient_name has been renamed to
  remainder_name.

Regards,
Thomas Mertes
