• How to convert a string to a number Variable and store the decimal

Hello!

Here's my problem!

I get information from a source that I can't control.  He sends me the number in to form chains.

Ex: 12,200.49

I tried usingval() but only get '12' because it stops when she sees a comma or a period.

I also tried using Replace() to remove the comma and period, but then my increase, because the last two digits are now a part of the number and either behind a decimal point.

Some examples of code

< cfset price = "12,200.49" >

< cfoutput >
#val (Price) #.
< cfset price = ' #Replace (Price, ",", "","ALL") # ">

< BR / >
#val (Price) #.
< cfset price = "#Replace(Price,".","","ALL") #" >
< BR / >
#val (Price) #.

< cfset price = #NumberFormat (Price, "_. _") # >
< BR / >
FINISHED WITH #Price #.

< / cfoutput >

The output of the code above is as follows:

12
12200
1220049
FINISHED WITH 1220049.00

So, you can see that 12,200.49 is now 1,220,049.00 because the two numbers when added.

What I would like to end by is a string '12,200.49' which is now a number like this \$12 200,49

• How to convert a string and use a rope as a property?

I have an array in the following format:

{ownsCar: 'true', ownsBike: 'true', ownsHouse: 'true'}

{ownsCar: ownsBike 'false',: 'true', ownsHouse: 'true'}

{ownsCar: 'true', ownsBike: ownsHouse 'false',: 'true'}

etc ............

And I need to test against each element, for example

If...

myDataGrid ["myItem"] .ownsCar is object (myCheckbox) .label

... then

If...

myDataGrid ["myItem"] .ownsBike is object (myCheckbox) .label

... then

If...

myDataGrid ["myItem"] .ownsHouse is object (myCheckbox) .label

... then

But I have to build my application where the property (for example 'ownsCar', 'ownsBike', 'ownsHouse') is a variable such as:

If...

myDataGrid ["myItem"] .myProperty is object (myCheckbox) .label

... then

I would like to browse my table, by counting the number of items and then use each element as a property.

How to convert the string (for example, "ownsCar") in a property "myProperty"?

OK, if I got this right what you need to do is introspection.

The easiest way to do this would be:

```for ( var propertyName:String in myObject ) {
// Do what you need with this here:
myObject[ propertyName ];
}
```
• [Oracle 8i] How to convert a string (timestamp) in a date?

I find it difficult to know how to convert a string to a date time stamp (or possibly several).

The timestamp is 20 positions, character (NOT NULL, CHAR (20))
in the format: YYYYMMDDHHMMSSUUUUUU
where Y = year, M = month, D = day, M = Minutes, S = seconds and U = microseconds

The reason why I want to convert it is so that I can compare a timestamp to each other (that is, I want to be able to find the MIN (timestamp), MAX (timestamp) and make comparisons of inequality).

Is this possible?

Thanks in advance for the help on this!

Hello

As Damorgan said, if all you want to do is find which is the earlier or later, then you can just compare the strings: they are in a format where it works.

If you need to do other things, such as compare to today date or see the difference between two of your lines of days, you will need to convert it to date. (He has no reason to convert them to numbers).

A new TIMESTAMP data type, which manages the fractions of a second, was introduced in Oracle 9.
Since you use Oracle 8 (depending on your subject line), or it must be
(1) ignores the microseconds, or
(2) use a separate column for microseconds.

Whatever it is, use TO_DATE to convert the first 14 characters in DATE:

``````TO_DATE ( SUBSTR (txt, 1, 14)
, 'YYYYMMDDHH24MISS'
)```
```

where txt is your column of type CHAR.
To convert microseconds to a number (between 0 and 999999):

````TO_NUMBER (SUBSTR (txt, 15))`
```

• How to convert a string literal function function valid

Hello

I have a situation where I need to get the built-in (sysdate/sysdate-1/sysdate-2) as variables. As the variable is taken as a string, it is considered as a string, not a function. Is it possible to convert the string literal in valid function.

Here is an example for better understanding. I used v_var to store the 'sysdate-1 "in the form of string literal. Try to change the value.

*/*-------------------------------------------------------------------------------------*/*
declare

v_var varchar2 (20): = ' sysdate-1';
date of v_var2;

Select v_var in the double v_var2;

dbms_output.put_line ('v_var2: ' | v_var2);

end;

• How to convert a string of data to a table 1 d

Dear all,

I wonder if someone can help me.

In the attached Elf, I have my program (in labview 8.6) who read the updates and the data of temperature for the time.

I want to use temperature update in a calculation.  How can I get the new temperature I think it's in a format string and convert it into table 1 d?

I tried, but the number I got the temperature wasn't the same temperature, which is shonw in the section of the program data.

Kind regards

You do not read the temperature, you read a binary file. You seem to be assuming that the string format, but do you really know? Nobody here can say since you do not have the file, if it is you need to use one of the functions of conversion of the string. And please, get rid of the local data variable. You're already usin shift registers. Do the same with the data from the file.

• How to convert the string with numbers in the table of Boolean 2D

Hello

I have input a string with comma separated numbers 1,192 (starting at 1).

This string must be converted to a table 2D-boolean. Each number that appears should be true, not true rest.

The 2D table consists of 4 times of 0.47 Boolean values.

1.48--> [0.47] numbers [0]
49.96--> [0.47] numbers [1]
Numbers 97.144--> [0.47] [2]
145.192--> [0.47] numbers [3]

If a '1, 49, 97 145' input string put all [0] [0.3] true.

How can it be easy/fast resolved?

Thanks for help

Break the string of numbers in a table of numbers.  (Spreasheet String to Array).

In a loop For, index with each issue of this table.  Use in the range and Coerce to see if it is in the range of numbers.  (You can put this in a loop For as auto good indexing through the ranges).  If it's in the range, then use subset replace table to activate the corresponding item in a real.  If this is not the case, do nothing.  Maintain the table of Boolean in a shift register.

Repeat this step for each number in your table.
