How to get the decimal part of a float?

Question

I need to extract the decimal part of a float number, but I get weird results:

float n = 22.65f;
// I want x = 0.65f, but...

x = n % 1; // x = 0.6499996

x

If you just want to print the number to 2dp you can use DecimalFormat.

DecimalFormat df= new DecimalFormat("#.##");
System.out.println(df.format(f));

If you want fixed point numbers internally use BigDecimal
