perform a bit cast from int to float in swift

To perform a bit cast from an integer to a float in Swift, you can use the bitPattern property of the Float type. Here's an example:

main.swift
let i: Int = 123456789
let f = Float(bitPattern: i)
print(f) // Output: 1.4544413e-23
86 chars
4 lines

In the above code, we declare an integer i and assign it a value of 123456789. Then, we create a new float f using Float(bitPattern: i). This initializes the new float by bitcasting the integer value i into its floating-point representation. Finally, we print the value of f.

Note that this type of bitcasting should be used with caution, as it relies on the underlying representation of the data and can produce unexpected results in some cases.
