Syntaxe

Sin(Nombre)

Paramètres

Nom Description
Nombre Ce paramètre permet d'indiquer l'expression contenant le nombre à traiter

Description

Cette fonction trigonométrique retourne le Sinus.

Algorithme

MODULE SIN(X)
   R ← X x X
   S ← 42.0
   BOUCLE POUR I ← 10 JUSQU'A 1
      S ← 4.0 x I - 2.0 + (-R) / S
   FIN BOUCLE POUR
   RETOURNE 2.0 x X x S / (R + S x S)

Exemple

Voici un exemple permet d'afficher les Sinus inférieurs à π :

  1. DROP PROCEDURE IF EXISTS WHILESIN;
  2. CREATE PROCEDURE WHILESIN()
  3. BEGIN
  4. DECLARE R DOUBLE  DEFAULT 0.0;
  5. WHILE R < PI() DO
  6. SELECT CONCAT("Sin(",R,")=",sin(R));
  7.         SET R = R + 0.1;
  8. END WHILE;
  9. END;
  10.  
  11. CALL WHILESIN();

on obtiendra le résultat suivant :
