Numbers and Strings

Numbers can be written as integers, decimal numbers, in scientific notation with an E preceding the power of ten, and as date-time values. A single period by itself is the missing numeric value.

For example, these are all numbers:

. 1 12 1.234 3E3 0.314159265E+1 1E-20

One or more characters placed within double quotation marks constitute a string. For example, these are all strings:

"Green" "Hello,\NWorld!" "54"

Notice that if a number is in quotation marks, it is a string, not a number. There are two functions you can use to change a number into a string or a string into a number.

•	Use Num() to convert a string into a number. For example:

Num("54");

Note: Num() cannot convert non-numeric characters, so it produces a missing value.

Num("Hello");

•	Use Char() to convert a number into a string. For example:

To preserve locale-specific numeric formatting in Num() or Char() output, include <<Use Locale(1). option as shown in the following example:

Char( 42,5,2, <<Use Locale(1) );

// results in the character value "42,00" in the French locale

Unicode Characters

JMP supports both Unicode UTF-8 and UTF-16 standards for encoding and representing text for most of the world languages. Refer to the The Unicode Consortium for code charts and details on the Unicode standard.

To display Unicode characters in JMP, precede the Unicode code for the character with ’\!’. For example:

•	Greek letter sigma (σ) in Unicode = U+03C3; in JMP, use \!U03C3

•	Greek letter mu (μ) in Unicode = U+03BC; in JMP, use \!U03BC

To use Unicode to express superscripts and subscripts:

•	subscript 1 (1) in Unicode = U+2081; in JMP, use \!U2081

•	superscript 2 (2) in Unicode = U+00B2; in JMP, use \!U00B2

To express x2 in Unicode, in JMP, use \!U0078\!U00B2.
