Round down in swift

Question

I would like to round a Double to a certain number of decimals always rounding down.

Example

rounding to .00 => 1.5679999 to 1.56

rounding to .000 => 1.5679999 to 1.567

round(1.5679999 * 100) / 100 //returns 1.57 round(1.5679999 * 1000) / 1000 //returns 1.568 

I want a Double not a concatenated String

Answer 1

Just replace round with floor!
