Convert 2.6 to a whole number?

When you converting a decimal to a whole number, precision will get lost (you lose the decimal part). The "converted" number will, of course, not be exactly the same as the original number.

You must decide, depending on your needs, whether you want to:

• Round to the nearest whole number (3 in this case).
• Round up (also 3 in this case).
• Round down (2 in this case).
