Topic Overview

Greetings! Are you ready to delve deeper into the universe of the Go language? Our current journey delves into a fundamental concept of programming languages: Data Type Conversion. Often, we need to transform one data type into another, similar to adjusting a spaceship's asteroid-floating-point measurements to fit the integer-based radar system. We will study both automatic and explicit conversions, pointing out potential traps and loopholes along the way. Let's power up our knowledge engines!

Automatic (Implicit) Conversions

Unlike many other languages, Go does not provide automatic type conversions. Consequently, each conversion between different types requires explicit syntax. This might seem restrictive, but the approach is designed to prevent subtle bugs.

Manual (Explicit) Conversions

There will be instances when we will need to fit a large floating-point number into an integer-based tuple, requiring explicit casting. Observe how we convert a float64 to an int:

Notice that the fractional part 0.25 was discarded during the process, leaving only 10 as the result.
