.11 * 100 trouble in C++

[zspirit]

My float variable contain .11 and I don't get the desired result of 11 from multiplication but simply numerica value .11 works.

short int test = .11 * 100; // test is right 11.

// case 2
float fVal = .11;
short int test = fVal * 100; // now test is .10

I tried various typcasting but it always is .10 when I use the float variable. How can I get the correct result?

compiler is VC++ 2005
