Specify decimal, scientific, or engineering formats or a custom format. When the worksheet column is set to Format = Numeric or Text & Numeric, the number of displayed digits is determined by a combination of these settings in the Column Properties dialog box: If the Data Type is not appropriate to the data, you risk losing precision in your numbers. For the same reason, you should verify the column Data Type before you enter or import data into a worksheet column. Select from the Data Type drop-down list.ĬAUTION: Data Types of less than Double(8) may cause problems with various math operations.In the Column Properties dialog, choose Format = Numeric.With the column selected, choose Format: Column from the Origin menu.Right-click on a selected column and choose Properties.To open the Column Properties dialog box: For instance, if you needed to save even more memory (upwards of an additional 50%), you could change columns to Format = Numeric with a Data Type of Real(4) (see the note of caution, below): When you are working with numeric data, you can adjust the amount of storage allocated to each data value by changing the Data Type setting in the Column Properties dialog box. While Text & Numeric generally supports Origin's custom display formatting, there are quirks and setting Format to Numeric eliminates some issues. In addition, if you are applying custom formats to a column of numeric data, you should change the column Format from Text & Numeric to Numeric. Select Use Numeric as Preferred Column Type.From the menu, select Preferences: Options.If you are concerned about maximizing system resources, you can configure Origin to use Numeric Double(8) for all columns in new worksheets: In most cases this difference will not cause problems with machine performance. The Text & Numeric format uses approximately 20% more memory than type Numeric Double(8). 5 Decimal, Scientific and Engineering Notation.2 Numeric Data Types and memory allocation.The place of the asterisk should match the place of the number specifying the fields in the input arguments. To specify the field width and precision outside the format specifier, use an asterisk (*) in place of the field width or precision fields of the formatting operator. If the field width w is higher than p+1+n, then the whole part of the output is padded to the left with either space or zero additional characters, calculated as w-(p+1+n).įield Width and Precision, Outside the Format Specifier.If the field width w is not specified, then the default value is calculated as per p+1+n, n is the number of digits in the whole part of an input value.of digits in the fractional part, then the fractional part is shown with added zeroes to the right of p digits. If the precision p is higher than the no.If precision p is less than the number of a digit in the fractional part of the input, then only p digits are displayed after the decimal point, and the output value is rounded off.If precision is not specified, then the default value is set to six.Let's examine with an illustrated example: And field width & precision define how a number should be displayed in the output. The formatting operators follow specific rules for formatting the output text. Representation of Unicode numeric value of the octal number, N \NĮxample: sprintf('\100') returns character for setting Field Width and Precision Representation of Unicode numeric value of the hexadecimal number, NĮxample: sprintf('\圆A') returns character 'j' To make special characters as part of the output text, use specific character sequences. Special characters are meant to serve particular purposes, so these cannot be used as ordinary text. Hexadecimal notation (unsigned, using lowercase letters A-F)ĭisplaying Special Characters in the Output Hexadecimal notation (unsigned, using lowercase letters a-f) The more compact of the %e or %f (insignificant zero do not print) No.Įxponential notation (using a lowercase e, as in 3.1415e+00)Įxponential notations (using a uppercase E, as in 3.1415E+00)
The conversion character is denoted by a single alphabetical character and appears last in the format specifier.
The conversion character is an only required field, and it specifies the notation of the output. And no space character is allowed in between the fields of formatting operator.The conversion character must always lead by a % percent sign.The conversion character is an only required field among all six fields.
A formatting operator can have a maximum of six fields-the conversion character, subtype, precision, field width, flags, and numeric identifier. The % percent sign always leads the formatting operator. Fields of the Formatting Operator in MATLAB
