What's wrong with:

String.Format("+{0}", myFloat);

?

Cheers

Hi Chad,

What if the float is negative?

This may be better:
String.Format( "{0}{1}", ((myFloat < 0) ? "-" : "+"), myFloat );

Assuming you want the sign of the number to be displayed rather than an
arbitrary '+', then try the following:

a.ToString("+#.###;-#.###;0");

Where 'a' is your variable. This is a format string with sections,
separated by semi-colons. The first section (+#.###) applies to
positive numbers, the second (-#.###) applies to negative numbers and
the last applies to zero.
