#Matlab format withou exponents code#

In general I can say that the code still works ok on. Yair Altman (198 days 18 hours ago): You didn’t say what code you were trying to run and what exactly didn’t work for you, so I cannot help you.The pattern directly corresponds to the settable properties listed above, and is very similar to the custom numeric pattern that is settable in Microsoft Excel. A description of the different pattern components can be found here. In addition, the DecimalFormat object provides methods that enable setting/getting a pattern that directly specifies how numbers should be parsed. RoundingMode – (default=RoundingMode.HALF_EVEN) a object that sets the manner in which numbers are rounded to fit the required number of digits.There are corresponding properties PositivePrefix and PositiveSuffix. Some bankers like to display negative numbers as “(value)” and this is easy to do using NegativePrefix and NegativeSuffix. NegativeSuffix – default = ”) the string to display to the right of a negative number.NegativePrefix – (default=’-‘) the string to display to the left of a negative number.Multiplier – (default=1) multiplies the number by the specified value before converting to string.MinimumIntegerDigits – (default=1) the minimum number of digits to display, padding with leading zeros if necessary.MaximumIntegerDigits – (default= intmax) the maximal number of digits to display to the left of the decimal sign.MinimumFractionDigits – (default=0) the minimum number of digits to display, padding with trailing zeros if necessary.Post-rounding trailing zeros are omitted. MaximumFractionDigits – (default=3) the maximal number of digits to display to the right of the decimal sign.Matlab’s built-in num2str does not use grouping. GroupingUsed – (default=true) a boolean flag that specifies whether or not to use the grouping sign at all.GroupingSize – (default=3) indicates how many integer digits should be grouped by the grouping (“thousands”) separator sign.

DecimalSeparatorAlwaysShown – (default=false) a boolean flag that specifies whether or not to display the decimal sign even for integer numbers.DecimalFormatSymbols – a object that sets the character symbols for such things as the decimal sign (“.” or “,” for example), grouping separator (“,” or ” ‘ ” or whatever), percent and per-mill signs, minus sign, infinity sign etc.Currency – a object that sets the currency symbol, international currency code and number of fractional decimal digits.Some of the interesting gettable/settable properties of the DecimalFormat object include (my Locale’s defaults are specified – your Locale might be different): Similarly, property values can be retrieved using either get(‘XYZ’) or the corresponding getXYZ() or isXYZ() Java methods (which are better). In most cases, we find that Java properties can be set using either of these manners, although using the Java accessor methods is typically safer and prevents some possible problems. In the simple code snippet above, note the two alternative manners in which I set the DecimalFormat object’s properties, once with the set(‘XYZ’,value) function, then using the corresponding Java accessor method setXYZ(value). In this case, we shall use the standard :

The solution was to use Matlab’s fully-documented built-in support for using Java objects. I had to find a generic cross-platform way to code this in Matlab in a way that will work for all users out-of-the-box (the application is compiled and distributed as an executable). Moreover, some data values (for example, FOREX exchange rates) need more than two decimal digits. The bank has branches in several countries and people naturally use different Locales on their computer. I have recently completed a consulting work for a bank in Switzerland where these limitations were very important. Customization of the decimal sign and thousands grouping sign is even more difficult. format does not enable customization of the number of decimal digits, and num2str and sprintf‘s ability to do so is limited.The functions always use the same manner to display the number, disregarding the user’s Locale. For example, the number 1234.56 is normally displayed as 1,234.56 or 1’234.56 or 1234,56 depending on your chosen Locale (which is determined by the local language and country). They do not take into account the user’s computer Locale settings.Unfortunately, these built-in functions, useful as they are for simple needs, have several limitations:

Matlab has built-in support for this using the fully-documented num2str, sprintf and format functions. We often need to display numbers, in GUI, text files or maybe the console window (Matlab Desktop).
