== Variable function ==
 
=== Description: ===
This function allow you to assign variable ( a floating point value or string) and using some operon (+ - * / ) to calculate or process it.
 
Section1:
Variable
Section2:
variable name
 
example:
:A, A2, AAA, BBB, xxx, abc,..... ( some of reserve word can't be assign as a variable)
:if there is brance "{}" inside the process string please refer to Brance process
 
reserve word:
:Field_Proc
:Field_Show or
:Date_Proc  ( see more help Example 4)
:&xxxxx  ( start with "&" character ) => see more help Smart Format
:ITTS_xxxx  ( start with "ITTS_" character )  => see more help for ITTS share memory

 
 
Command :
:Str=:Assign string to an Variable ( but not suport >,<,>=,<=,== function)  (see example 0)
:=:Assign variable =some value. (Extend function:please see Example 5)
 
Remark:
:num of variables: limited under 256
:name length limited under 64
:variable type is Double (range from : 5.0 x 10^-324 .. 1.7 x 10^308)
 
:num of  string variables limited under 256
:name length limited under 64
:string variables string length : no limited
 
運算元
:abs: variable =ABS(P3),  absolute value
:+:variable = P3+P4
:-:variable = P3-P4
:*:variable = P3*P4
:/:variable = P3/P4
AND  : variable = P3 and P4  ( only allow integer). 0x01 and 0x10 => 0x00
OR  : variable = P3 or P4  ( only allow integer).      0x01 or 0x10 =>0x11
XOR  : variable = P3 xor P4  ( only allow integer). 0x11 xor 0x10 =>0x01
    NOT : variable = NOT( P3)  ( only allow integer)
P4:  show number of nibbles. 
P3= 0x0011, p4 =4    =>65518 (0xFFEE, )
 
MIN:variable =MIN(P3,P4)
MAX:variable =MAX(P3,P4)
CTF:variable = SQRT(P3*P4)  , formula to get center frequency
POWER: variable = power(P3,P4)  ,
SQRT:variable = SQRT(P3) , sqrt (2) = 1.414
 
>:Judgement    bigger
<:Judgement  smaller
>=:Judgement   equal or bigger
