如何在Go中打印浮点数的二进制表示形式？

Question

The fmt package allows us to print a binary representation of integers with %b. How to get an equivalent result for floats instead of the scientific notation?

fmt.Printf("%b", 52) // 110100
fmt.Printf("%b", 52.0) // 7318349394477056p-47

Answer 1

You can get the raw bits of a float with the math package using math.Float64bits or math.Float32bits. Combining this with the %b formatting verb will display the binary representation of the float.

fmt.Printf("%b
", math.Float64bits(52.0))
