Crystal Report - urgente>>numero=letra

Hola. como se hace la formula para que si en una tabla me pasan un campo numero lo iguale a una cadena de caracteres que yo quiera. Gracias. Un saludo

Si te refieres a esto:
1254= un mil docientos cincuenta y cuatro
entonces usa esta función:
towords(1254)
ótowords(tabla.camponumerico)

Hola. me refiero a si es un 0 sea = a no y si es 1 uno = a si. Gracias.

Creas una formula, dentro de ella se podría colocar de la siguiente manera:

if {tabla.campo}=0 then
"no"
else
"si"

ó

if {tabla.campo}=0 then
"no"
else
if {tabla.campo}=1 then
"si"


Esto es en sintaxis crystal

Muchas Gracias.
