While playing around, I found the round() function in swift. It can be used as below:
round(0.8) Which will return 1, as expected. Here's my question:
how do I round by thousandths in swift?
I want to be able to plug in a number, say 0.6849, and get 0.685 back. How does round() do this? Or, does it not, in which case, what function does?
970
Rules for Rounding Here's the general rule for rounding: If the number you are rounding is followed by 5, 6, 7, 8, or 9, round the number up. Example: 38 rounded to the nearest ten is 40. If the number you are rounding is followed by 0, 1, 2, 3, or 4, round the number down.
To round a double to the nearest integer, just use round() .
The ROUND function rounds a number to a specified number of digits. For example, if cell A1 contains 23.7825, and you want to round that value to two decimal places, you can use the following formula: =ROUND(A1, 2) The result of this function is 23.78.
You can do:
round(1000 * x) / 1000 If you love us? You can donate to us via Paypal or buy me a coffee so we can maintain and grow! Thank you!
