Adding singles

[bartj]

Hello,

Using VS2008, I am adding 2 singles and am getting a bad result. See below

Dim stepsize As Single
Dim temps As Single
Dim startf As Single
dim i as integer

' some code here sets startf to 162.7
' some code here sets stepsize to .01

temps = startf

debug.print (temps.ToString) ' shows "162.7"
Debug.Print(stepsize.ToString) ' shows ".01"

for i = 1 to 11
Debug.Print(temps.ToString)
temps = temps + stepsize
next

Here is the debug output from the loop!!!!

162.7
162.71
162.72
162.73
162.74
162.75
162.76
162.77
162.78
162.7899 <<<< What is this ???
162.7999 <<<<< And this ???


Any insights or fixes???
Thanks,
bartj
