Swift 2.0 Study Notes (day 13)--integer and float type for data types

       Swiftprovide8, -, +, -a signed and unsigned integer in bit form. These integer types followCthe naming conventions of language, I summed upSwiftintegral type in:

Example of an integral type:

Print ("UInt8 range: \ (uint8.min) ~ \ (Uint8.max)")

print ("Int8 range: \ (int8.min) ~ \ (Int8.max)")

        print ("UInt range: \ (uint.min) ~ \ (Uint.max)")

Print("UInt64 range: \ (uint64.min) ~ \ (Uint64.max)")

Print ("Int64 range: \ (int64.min) ~ \ (Int64.max)")

Print ("Int range: \ (int.min) ~ \ (Int.max)")

The output results are as follows:

UInt8 range:0 ~ 255

Int8 Range: 128 ~ 127

UInt range:0 ~ 18446744073709551615

UInt64 range:0 ~ 18446744073709551615

Int64 Range: 9223372036854775808 ~ 9223372036854775807

Int Range:-9223372036854775808 ~ 9223372036854775807

The above code is through an integer min and the Max Property calculates the range of each type.

Floating-point types are primarily used to store decimal values, and can be used to store large integers. It is divided into floating-point (float) and double-precision floating-point (double), double-precision floating-point numbers use more memory space than floating-point number, can represent the range of values and precision is also relatively large.
