I have a string which represents a floating-point number. When i try to convert it to float number i don't get the exact floating point number. my example code is given below.

string s_num = "666890.23"
float f_num = float.Parse(s_num);

The result is f_num = 666890.25

Why is this happening. Why am I not getting the exact figure.
Please help me out.

use System.Convert.ToDouble(s_num) and change float to double...

[unreal_origin]

according to this website floats in C# are only Precise to 7 digits
C# Float

if you were to do something like
string s_num = "66690.23"
float f_num = float.Parse(s_num);

The result is f_num = 66690.23
it is better to just use double. Less problems

double.Parse(s_num);

hope that helps
