F # Tutorials-Numeric constants

So far, although we've experienced the difference between F # integers and floating-point numbers, what's the difference between short, int, double float? Try to look at the following code:

let　num1　=　10s
let　num2　=　10
let　num3　=　10L
let　num4　=　10.0
let　num5　=　10.f

These numeric constants are written in a similar notation to C #.

But is this consistent with what we expected, and can be confirmed by practice. After a little investigation, I found the F # Interactive feature. You can use the ALT + ENTER to display the F # Interactive window under the main window to investigate them. The output results are as follows:

val　num1　:　int16
val　num2　:　int
val　num3　:　int64
val　num4　:　float
val　num5　:　float32

F # 's float is equivalent to C # 's double. And float32 is the float of C #, indeed a bit confusing. But actually using float32 almost no, 10.0 similar constant declarations are OK.

Other types of wording are as follows:

10u　　　　　　　　　　　　　　　　　　　　　//　uint
10us　　　　　　　　　　　　　　　　　　　　//　ushort
10ul　　　　　　　　　　　　　　　　　　　　//　ulong
120y　　　　　　　　　　　　　　　　　　　　//　sbyte
0xFFuy　　　　　　　　　　　　　　　　//　byte

Because it is. NET language, we can also try the decimal type:

Let NUM6 = 10.5m
