`IsNumber()` | whether the value is a number `IsNumber()` | N/A

Note that, an integer value may be obtained in various ways without conversion. For example, A value `x` containing `123` will make `x.IsInt() == x.IsUint() == x.Int64() == x.Uint64() == ture`. But a value `y` containing `-3000000000` will only makes `x.int64() == true`. Note that, an integer value may be obtained in various ways without conversion.
