C # retains two digits after decimal point (method Summary)

The simplest use:

float i=1.6667f;

String Show=i.tostring ("0.00"); Result 1.67 (rounded)

Other similar methods:

String Show=i.tostring ("F");//"F2", "F" is case insensitive

String Show=string.format ("{0:f}", i);//can also be F2, or "{0:0.00}

Float J=math.round (i,2);

String show=j.tostring (); Result is 1.67

Decimal. Round (decimal. Parse (i), 2); Results 1.67

System.Globalization.NumberFormatInfo NFI = new System.Globalization.NumberFormatInfo ();

Nfi. numberdecimaldigits=2;
String result=i.tostring ("N", NFI);//Result 1.67

All of the above methods are rounded, and below are the direct truncation:

float i = 32.16667F;

int j = (int) (i * 100);

I= J * 0.01f;//Results 32.16
