I have a input field, and I want to create a regex that only receive input value from 0.00 to 100.00(include both). I have created a regex check:
^1?\d{0,2}(\.\d{1,2})?$
But with this one, it not only accept values from 0.00 to 100.00 but also accept the input from 100.01 to 199.99.
How can I set a condition that if there are three digital before the dot, it can be only 100 and the decimals part is 00 or 0 only if having decimals?
So 100.00, 100.0 or 100 are the only accept for the values over 99.99 and the input between 100.01 to 199.99 is not pass.
Here are some passed input:
100
100.00
100.0
3
0
0.00
5.2
8.21
37.23
Here are some not passed:
40.323
100.50
101.50
199.99
40.
100.
This should work:
^((?:100(?:\.00?)?)|(?:\d\d?(?:\.\d\d?)?))$
It matches:
x
x.x
x.xx
xx
xx.x
xx.xx
100
100.0
100.00
You can get the match via directly match or with the first capturing group :)
P.S. BTW, #Ouroborus's solution (in comments) also works, and his solution unexpectedly having the exact same length as mine lol:
^(?=.)(100(\.0{1,2})?|\d{1,2}(\.\d{1,2})?)$
You can match 0 - 99 with 1 or 2 optional decimals or 100 with optional .0 or .00
^(?:\d\d?(?:\.\d\d?)?|100(?:\.00?)?)$
The pattern in parts:
^ Start of string
(?: Non capture group
\d\d? Match 1-2 digits
(?:\.\d\d?)? Optionally match . and 1-2 digits
| or
100(?:\.00?)? Match 100 or 100.0 or 100.00
) Close non capture group
$ End of string
Regex demo
Try this:
^(100(\.00?)?|\d\d?)(\.\d\d?)?$
See live demo.
Regex:
^ = start
(100|\d\d?) = literal 100 or 1 or 2 digits
(\.\d\d?)? = dot then 1 or 2 digits, all optional
$ = end

I need a RegEx for a numeric value that starts at 60.00 and has no upper limit.
I have used the below RegEx for numbers between 0.00 and 60.00, but now I need a similar expression for all numbers over 60.00 with 2 decimal places
^(?=.)(?:(?:(?:0|[1-5]?\d)?(?:[,.]\d{1,2})?)|60(?:[.,]00?)?)$
You can use
^(?!60(?:\.00?)?$)(?:[6-9][0-9]|[1-9][0-9]{2,})(?:\.[0-9]{1,2})?$
Or, if you cannot afford lookaheads:
^(?:60(?:\.(?:0?[1-9]|[1-9][0-9]))|(?:6[1-9]|[7-9][0-9]|[1-9][0-9]{2,})(?:\.[0-9]{1,2})?)$
See the regex demo #1 / regex demo #2.
Details:
^ - start of string
(?!60(?:\.00?)?$) - a negative lookahead that fails the match if the string is 60, 60.0 or 60.00
(?: - start of a non-capturing group:
[6-9][0-9] - 60 to 99 number
| - or
[1-9][0-9]{2,} - a digit from 1 to 9 and then two or more digits (100 and more)
) - end of the group
(?:\.[0-9]{1,2})? - an optional sequence of a . and one or two digits
$ - end of string.
I need Help for currency regex in Angular.
I'm not really good at regex.
What I want is a regex that:
allows comma as digital-group-separator, but not in the beginning or the end.
allows only 2 digits rounded after decimal point.
allows only one decimal point and not in the beginning or the end.
not allows 0.00 or 0.
This is my regex:
(?=.*?\d)^\$?(([1-9]\d{0,2}(,\d{3})*)|\d+)?(\.\d{1,2})?$
but this regex allows 0.00
any one here please help thanks

^ - start of string
(?![0.,]+$) - a negative lookahead that fails the match if there are one or more 0, , or . chars till end of string
(?:0|[1-9]\d{0,2}(?:,\d{3})*|[1-9]\d* - either of the three alternatives:
0 - zero

[1-9]\d{0,2}(?:,\d{3})* - one to three digits with the first one being non-zero, and then 0 or more repetitions of a comma and then three digits

(?:\.\d{1,2})? - an optional sequence of a . and then 1 or 2 digits
$ - end of string.
I have a text box. This text box should accept only values between 5 and 555. But I am unable to achieve it.
I have tried the below:
/^[0-9]{5, 500}$/
Kindly help me in this case.
What you need:
^([5-9]|\d\d|[1-4]\d\d|5[0-4]\d|55[0-5])$
It uses | to have 3 different statements to deal with 1-digit, 2-digit and 3-digit numbers.
Live Demo on Regex101
How it works:
^ # String starts with ...
(
[5-9] # 1-Digit - Any digit 5 or over (5 to 9)
| # OR
\d\d # 2-Digit - Any 2 digits (since any 2-digit number will be within your range)
| # OR
[1-4]\d\d # 3-Digit (below 500) - Any digit 1 to 5 (100 to 500), followed by any 2 digits
| # OR
5[0-4]\d # 3-Digit (above 500, below 550) - 5, followed by any digit 0 to 4 (500 to 540),
# followed by any digit
| # OR
55[0-5] # 3-Digits (550 or above) - 55, followed by any digit 0 to 5 (550 to 555)
)
$ # ... String ends with
This should work (though not recommended)
^(55[0-5]|5[0-4][0-9]|[1-4][0-9][0-9]|[1-9][0-9]|[5-9])$

Proof of correctness
I'm looking for a regex to validate if numbers are below 20 000.
I can't find the right solution, I have so far this:
(^([1-9]([0-9]{0,3})|20000)$)
Which works quite ok but as soon as it gets to 10 000 it gives no matches. So I have a gap from 9 999 - 20 000.
What am I doing wrong? I don't use regex for these situations, but the 3th party program required regex for such..
Thanks!
Your regex - ^([1-9]([0-9]{0,3})|20000)$ - matches numbers from 1 till 9999 and 20000.
You may use
^([1-9]\d{0,3}|1\d{4}|20000)$
See demo
Breakdown:
^ - match start of string
([1-9]\d{0,3}|1\d{4}|20000) - match one of the alternatives:
[1-9]\d{0,3} - 1 to 9 followed with 0 to 3 any digits (from 1 till 9999)
1\d{4} - 1 followed with any 4 digits (to match 10000 - 19999)
20000 - literally 20000
$ - match the end of string
I've got this:
^([01]?\d{0,4}|20000)$
Which match any number from 0 to 20 000 and allow the user to use number with leading 0 Live Demo
The ([1-9]([0-9]{0,3}) part is designed to match all numbers strictly below 2000 but you define it as: "A digit one to nine followed by zero to three digits". Now 10 000 is a one followed by four zeros: you can rewrite the part as:
[1-9][0-9]{3}|1[0-9]{4}
The full regex is now:
^[1-9][0-9]{3}|1[0-9]{4}|20000$
I want to match:
0.01
0.12
1.00
1.12
12.00
12.34
But not:
0
0.00
.00
.12
To get price value which can not be zero.
I have written this regex:
/(^\d{1,}\.\d{2}$)|(^\d{1,}$)/
But it matches:
0
0.00
which I want to eliminate.
I've also tried with exclusion rules like ^(?!0)(?!0\.00)\d{1,}\.\d{2}|\d+$ but no success.
You want to match a value with decimal 2 digits but not 0:
^(?![.0]*$)\d+\.\d{2}$
The negative lookahead checks, if the string does not consist of only 0 and .
\d+\.\d{2} assures the desired formatting: One or more digits followed by a . followed by 2 digits.
Test at regex101.com (also see explanation on the right side)
To also allow 1, 2.2 change the last part to \.\d{1,2} and make it optional:
^(?![.0]*$)\d+(?:\.\d{1,2})?$
Test at regex101.com
(?=.*?[1-9])(^\d+\.\d{2}$)|(?=.*?[1-9])(^\d{1,}$)
Try this.Just added (?=.*?[1-9]) to negate 0.See demo.
http://regex101.com/r/yA1jY6/1
You could try the below regex.
^(?!0(\.00)?$)\d+(?:\.\d{2})?$

Negative lookahead at the start won't allow 0 or 0.00
