| Kyros said: you have to round up. No you haven't. Rounding to the nearest decimal, rounding up or rounding down are three equally valid options that are used in different situations. IF this is done for prices in stores its generally rounded down. If its your pay amounts are normally rounded up and grades in school are often rounded to the nearest number. There are no mathematical rules how you have to round. |
Yep, and in bankers rounding, they randomly round .5 up or down.
Rounding means to take something to the next decimal place up. How you take it there is up to you.
edit: "next decimal up" means loosing an order of magnitude, not to a higher value.
