Swift's string interpolation means you can convert all sorts of data – including integers – to a string in just one line of code: let str1 = "\(myInt)" It corresponds to Int32 on a 32-bit platform and to Int64 on a 64-bit platform. Glossary             int(num + 0.5) If you want this to work properly for negative numbers use: ((num > 0) - (num . Source: www.w3schools.com. Basic casting like this does not work because these types are not primitives, unlike floats and ints in Objective-C var float: Float = 2.2 var integer: Int = float as Float But this produces the following To convert a float value to an Int, we can use the Int() constructor by passing a float value to it. Swift Float is used to … Swift Standard Library; On This Page. Also notice how Swift chose to put the floaing point values in the floating point registers s even though the general purpose registers x would have had enough space to store these values. Floating-point numbers cannot represent all the numbers. About             For example, the string "Bob" cannot be converted to an integer. Core Graphics; On This Page. Unfortunately, I can’t seem to find any resources on built in functionality to do so. var myInt = 5; var myDouble = 3.4; If I want a double for example in my result. For example: import math f=math.floor(2.3) Now f returns: 2.0 What is the safest way to get an integer out of this float, without running the risk of rounding errors (for example if the float is the equivalent of 1.99999) or perhaps I should use another function altogether? ios - float - swift string to int .
