ITTS:ITTS Scrip:Variable

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
• <=:Judgement equal or smaller
• ==:Judgement equal
• <>:Judgement not equal
