Display Float as String with at Least 1 Decimal Place

Question

I want to display a float as a string while making sure to display at least one decimal place. If there are more decimals I would like those displayed.

For example:

Answer 1

This solution is similar to what other are saying, but I prefer to use string.Format. For example:

float myFloat1 = 1.4646573654;
float myFloat2 = 5;
Console.WriteLine(string.Format("Number 1 : {0:0.00##}", myFloat1));
Console.WriteLine(string.Format("Number 2 : {0:0.00##}", myFloat2));

// Newer Syntax
Console.WriteLine($"{myFloat1:0.00##}";
Console.WriteLine($"{myFloat2:0.00##}";

This would produce :

Number 1 : 1.4646
Number 2 : 5.00
Number 1 : 1.4646
Number 2 : 5.00
