Okay I making a program where I input and output prices and I would like to know how to make the decimal go to only 2 places. I've already tried using the variable as a currency type but it still doesn't work. |

You'll want to look into either rounding, or truncating. |

Understand why many languages call functions that do just this kind of thing "ceil" and "floor". |

The Currency just provides a different method of storage for your numbers, since you wouldn't use floating-point numbers things such as currency. As for the decimal places, look into the FormatCurrency() function. |

you don't need currency. to round of to 2 decimal places use the format command and inside the brackets the name of the variable you want to round to 2 decimal places and "0.00" Example
if you want to round to 3 decimal places you would add an extra 0. and so on. |

Indeed. Never ever use floating point numbers for currency. If you feel tempted to do so, just watch the movie Office Space. |

Floating point numbers, as basically as you can get, are numbers with decimals, for example: 1.56 0.065 16342.6 You could have found this out from a simple Google/Wikipedia search. |
