[RBASE-L] - Rounding REAL vs DOUBLE

[Victor Timmons]

I am doing a very simple formula that does some rounding.

R>SET VAR vUpdateAmount REAL = .01
R>SET VAR vBookListPrice CURRENCY = 3.50
R>SET VAR vBookListPrice2 DOUBLE = NULL
R>SET VAR vBookListPrice2 = .vBookListPrice
R>SET VAR vBookListPrice2 = ((.vBookListPrice2 *  
.vUpdateAmount)+.vBookListPrice2)
R>SHO VAR vBookListPrice2
     3.5399999921769
R>SET VAR vBookListPrice2 = (ROUND(.vBookListPrice2,2))
R>SHO VAR vBookListPrice2
     3.53

If I change vUpdateAmount to a DOUBLE I get the correct results 3.54
Why is that?? Isnt .01 = .01 wheather is a REAL or a DOUBLE?? Could 
someone run this a let me know if they get the same results?

R>SET VAR vUpdateAmount DOUBLE = .01
R>SET VAR vBookListPrice CURRENCY = 3.50
R>SET VAR vBookListPrice2 DOUBLE = NULL
R>SET VAR vBookListPrice2 = .vBookListPrice
R>SET VAR vBookListPrice2 = ((.vBookListPrice2 *  
.vUpdateAmount)+.vBookListPrice2)
R>SHO VAR vBookListPrice2
     3.535
R>SET VAR vBookListPrice2 = (ROUND(.vBookListPrice2,2))
R>SHO VAR vBookListPrice2
     3.54
