如果确定any类型实际上是一个字符串或可以转换为字符串的类型(例如实现了fmt.Stringer接口的类型),可以使用类型断言: go func anyToString(v any) (string, error) { if str, ok := v.(string); ok { return str, nil } return "", fmt.Errorf("cannot convert type %T to string", v) } 2. ...
How to Convert string to float type in Go? ParseFloat converts the string s to a floating-point number with the precision specified by bitSize: 32 for float32, or 64 for float64. When bitSize=32, the result still has type float64, but it will be convertible to float32 without changin...

Integers and strings are converted to each other on many different occasions. This post will provide the ways we can convert an integer to a string in Go. The naive typecasting We may try doing a simple type conversion using the string() function to convert an integer to a string. It wi...

optimizations like bounds check elimination and common subexpression elimination. We observed a 5–35% speedup across our benchmarks. For now, the new backend is only available for the 64-bit x86 platform (“amd64”), but we’re planning to convert more architecture backends to SSA in future...
