Re: product() unexpected result

/* OE */ 
include std/math.e 
? product( {} ) 
--> 1 

/* p64t Phix */ 
? product( {} ) 
--> 0 

example ''arithmetic'' thinking

Lets say I want to estimate how much redymix concrete I must order:

vol1 = product( { 1,2,3 } ) 
--> 6 
// I order 6 cubic meters of concrete 

/* Phix */ 
vol2 = product( {} ) 
-- 0 
--> zero 
// no dimensions, I do not order truckloads of concrete 

/* OE */ 
include std/math.e  
vol3 = product( {} ) 
-- 1 
--> one 
 
-- I order a cubic meter of redymix I don't know what do with 

example ''mathematical'' thinking

• x⁰ = 1
• sqrt( -1 )
  = j (electrical thinking)
  = i (math thinking)
• ...
• product( {} )
  = 1
  = 0

In ''math'' I am open to various ideas.

needed

• OE and Phix not the same
• an argument to select mode of operation is needed

be well
