There's currently a thread at the LB Community Forum discussing the precision of floating-point numbers. Somebody has discovered a strange feature of LB:
Code:print using( "#.######################", (1/7)*7 )
print using( "#.#######################", (1/7)*7 )
LB 4.04 gives:
1.0000000000000000000000
0.99999999999999991611392
In other words attempting to print 23 decimal places rather than 22 produces a less accurate result!
LBB behaves sensibly, the output being:
1.0000000000000000000000
1.00000000000000000000000
I was aware of an anomaly when USING is used to format integers in LB:
Code:n = 12345678901234567890
print using( "#######################", n )
LB 4.04 outputs:
12345678901234567168
whilst LBB outputs:
12345678901234567890
but the misbehaviour with floating-point numbers is a new one on me.
