What is digital formatting and digital formatting? It is to convert a data type to another type. For example, to convert an integer to a floating point type, formatting means to convert several types of data into one type. Different types of storage have different lengths and there will be Errors During computation. Retain four decimal places: You can also use the number_format () function.

also set to 2048-bit, according to your own needs to choose. However, it is important to note that the use of the public (PrivateWhen the key is encrypted, the length of the string that needs to be encrypted is required, in terms of 1024-bit key length, the length of the string that needs to be encrypted cannot exceed 117 characters, and the formula is calculated as: 1024/8-11 = 117. Therefore, in the encryption of long strings, you need to use the method of Shard encryption, this need to note,
