在Golang中将整数转换为浮点数

如何将整数值转换为float64types?

我试过了

float(integer_value) 

但是这不起作用。 在Golang.org上找不到任何包。

我如何从整数值获取float64值?

没有floattypes。 看起来你想要float64 。 如果只需要单精度浮点值,也可以使用float32

 package main import "fmt" func main() { i := 5 f := float64(i) fmt.Printf("f is %f\n", f) } 

为了完整起见,这里是一个描述所有types的golang文档的链接 。 在你的情况下,它是数字types:

 uint8 the set of all unsigned 8-bit integers (0 to 255) uint16 the set of all unsigned 16-bit integers (0 to 65535) uint32 the set of all unsigned 32-bit integers (0 to 4294967295) uint64 the set of all unsigned 64-bit integers (0 to 18446744073709551615) int8 the set of all signed 8-bit integers (-128 to 127) int16 the set of all signed 16-bit integers (-32768 to 32767) int32 the set of all signed 32-bit integers (-2147483648 to 2147483647) int64 the set of all signed 64-bit integers (-9223372036854775808 to 9223372036854775807) float32 the set of all IEEE-754 32-bit floating-point numbers float64 the set of all IEEE-754 64-bit floating-point numbers complex64 the set of all complex numbers with float32 real and imaginary parts complex128 the set of all complex numbers with float64 real and imaginary parts byte alias for uint8 rune alias for int32 

这意味着你需要使用float64(integer_value)
