In Go, random numbers are generated using the math/rand package for pseudo-random numbers or crypto/rand for cryptographically secure pseudo-random numbers.

In Go, there isn’t a built-in function that directly rounds numbers to a specific number of decimal places in the math package.
In Go, complex numbers are handled using the built-in complex, real, and imag functions, along with complex64 and complex128 types (representing 64-bit and 128-bit complex numbers respectively).
