So your rounded numbers will usually again have many more decimals. This potential difference between the true value of a floating point number and how it's represented by the Swift language is important to remember when dealing with floats: 5-7, 9-11) Computes the nearest integer value to arg (in integer format), rounding halfway cases away from zero, regardless of the current rounding mode. This can be used as an index. To convert a float value to an Int, we can use the Int() constructor by passing a float value to it. Note the truncation in the latter example – there are more digits than can fit. 1-3) Computes the nearest integer value to arg (in floating-point format), rounding halfway cases away from zero, regardless of the current rounding mode. There are also other, probably more typical, situations where you may prefer Decimal.Decimal math is generelly preferred for example when dealing with currency, and you may want to decode directly into such a type. let x: Double = 21.25 let y = Float(x) print if my value is 8.25 then automatically it be rounded up to 8.5 and if value is 8.75 then it should become 9 Posted 20-Sep-11 23:14pm Qureshali … If you’d like to learn how to round the value of floating point number to a desired decimal place and convert it to string, then check out our floating point precision in Swift String tutorial.
