>If I remember my math , when rounding a number which is EXACTLY half way (in this case 0.0050000), the rounding rules get strange. For the round() function' I always add a five to the next decimal place to force the number to be rounded up. This removes erratic behavior of the ROUND function for numbers which fall exactly at the midpoint. For this case I would use :

>ln_round = ROUND(ln_round,2)

Shouldn't the operation here be truncation following addition of 0.005, otherwise this will always cause round up. Consider 1.0001, rounded to 2 dp this should be 1.00, if 0.005 is added, then calculation is round( 1.0051, 2 ) which should be 1.01, the wrong result.
