Description

inf is considered a number in TOL when running on linux but not when running on windows.

The following code:

Real {
  WriteLn("inf="<<inf);
  Real inf = 2;
  Real b = 3;
  If(inf<b, WriteLn("2 < 3"),WriteLn("2 > 3") );
  inf
};

will output:

  • on linux: 2>3
  • on windows: 2<3

La sentencia 

Real inf = 2;

debería dar un error.

Habría que comprobar si asa lo mismo con otros números especiales como nan

comment:5 Changed 14 years ago by Víctor de Buen Remiro

también sería bueno que en el interfaz salga resaltada como palabra clave inf

Existen muchos problema de compatibilidad hacia atrás por lo que resulta demasiado complicado cambiar todo el código que utiliza variables llamadas inf, INF, Inf o cualquier otra combinación de mayúsculas y minúsculas.

Sería conveniente deshacer también el resaltado de esta palabra. Véase [3267]

Ya estaba hecho.

(In [3280]) Se elimina el resaltado en tolbase de la palabra "inf".

(In [3289]) refs #1004, el PutValue de "inf", "+inf", "-inf" debe resultar en un valor desconocido.

Parece ser que de algún modo el problema persiste. Véase ​MMS#712.

comment:18 Changed 14 years ago by Pedro Gea

El problema puede estar relacionado con el comportamiento diferente de la sentencia:

Text FormatReal(1/0);

en los distintos operativos.

(In [3683]) closes #1004, la representación Text de los infinitos 1/0 y -1/0 es evaluable en la gramática Real dando como resultado el Real correspondiente.
