vasant bSubject: XSLT formatting number issue
Author: vasant b
Date: 07 Jan 2009 05:55 AM
I would like to format a number. The number should contain 6 digits after the decimal. However it should be dynamic. As soon as a single number is infinite, the number must be rounded. E.g. 1.3333333 should be set to 1.34; 1.543200 --> 1.5432; 1.000000 --> 1. Please help me in with this issue.

Thanks in advance,
Vasant

Hi Vasant,
provided that the rounding of 1.333333 can never be 1.34, you are looking for format-number().
If you write

<xsl:value-of select="format-number(1.36666666,'#.######')"/>
<xsl:value-of select="format-number(1.543200,'#.######')"/>
<xsl:value-of select="format-number(1.00000000,'#.######')"/>

you will get 1.366667, 1.5432 and 1

Thank you Alberto!!

But in case the number becomes infinite, ( e.g 1.33333333333....) our business requirement says it should be rounded ( e.g 1.34)

1.344444444444.... --> 1.345
1.2223333333333333.... -> 1.22234

Is this possible?. Thanks a lot for your support.

Vasant

Why would you ever round 1.333333 to 1.34? The last three would
round down, not up. To do otherwise is mathematically incorrect.

Hi Tony,

The number that I would like to format can result from two situations.

Manual :- In case of manually entered in a front end, I need to format it to 6 digits.

Automatic :- It may be a result of divison operation
for example 4/3 --> 1.33333333333........ In such situations I need to round it to 1.34.

Thanks,
Vasant

I realize that the customer is always supposed to be right, but I'm
sorry but in this case rounding 1.33333 -> 1.34 is just plain wrong.

1.33333 should at the least be rounded to 1.33. A trailing 3 should
never be rounded up.

Are you SURE that is a business requirement? We ask because in order
to find an algorithm that does what you want, we really have to
understand your process.

Hi Tony,

I am sorry. My requirement is as follows.


1.33333333333333... --> 1.33
1.11122222222222... --> 1.11122
1.55555555555555... --> 1.56
1.88888888888888... --> 1.89
1.28966666666666... --> 1.28967

In every other cases ( i.e when the number is not infinte)it shoud be rounded to 6 decimals.

for ex :- 1.12345678 --> 1.123456


Thanks a lot for your support.

I'm not sure I'm following what you are trying to do; but these formats will output the numbers the way you are looking for:
<xsl:value-of select="format-number(1.33333333333333, '#.##')"/>;
<xsl:value-of select="format-number(1.11122222222222, '#.#####')"/>;
<xsl:value-of select="format-number(1.55555555555555, '#.##')"/>;
<xsl:value-of select="format-number(1.88888888888888, '#.##')"/>;
<xsl:value-of select="format-number(1.28966666666666, '#.#####')"/>

Hi,

The number is not known at the begining. I would be reading it from an XML node. I should handle it based on the value of the node. Please see an example below.

For example I would be reading it from the XSL path '/Shares/share/rate'. So based on the value of the rate, I need to format it. In otherwords, i need to handle it dynamically.

Thanks,
Vasant

...handle it as a string (string-length, substring, ...), check its length, number of digits, and use the formatting logic that better suites your needs.
