B4A Question Rounding Numbers: Round2 or Numberformat2 - Roger Daley Nov 11, 2014 (1 reaction)This is an answer to a question raised in my mind by a comment from Erel, that I should not use Round2 but use Numberformat2 for rounding numbers.
Most of us are taught that for digits below 5, round down, for 5 and greater round up.
IE 4.725 to 2 decimal places gives 4.73. This is the result given by Round2.
Numberformat2 gives the result 4.72 after a bit of research I found... places is 4.72. 4.735 to 2 decimal places is 4.74.
Numberformat2 gives these results.
