[Solved] convert float to string with four numeric value [closed]

Question

You need simply enforce result string to show more zeroes if need.

var a = 20.0f; 
a.ToString("00.0000", CultureInfo.InvariantCulture) 
//2 digits before and 4 digits after (.)

Pay attention on fact that in your case the value may not be exactly 20.0, but something like 20.0012. In these cases you need to first convert it to exact 20.0, after format it to string.
