There are three possible ways to specify the desired precision: … WebRust supports floating-point numbers. That’s to say, numbers with a decimal point. The f32 type is a single precision floating point number, and f64 is a double precision floating point number. If you’re familiar with other programming languages such as the C family, f32 is like a float and f64 is like a double. Example:
