Declares one or more Float (single precision 32 bit floating point) variables.
To declare Float variables
Float {identifier} [… {identifier}]
Where
Where {identifier} is the name of a new Float variable. The first {identifier} is required.
{identifier} may be between 1 and 4096 characters in length, must start with a letter, and may not contain spaces. Recommended characters are 0-9, a-z, A-Z and _ (underscore).
To declare array variables of type Float
Float{dimension-list} {identifier} […{identifier}]
Where
{dimension-list} is a list of one or more array dimensions for the array. A dimension list is declared using square brackets []. One pair of brackets is used to declare each dimension. If the array is static, then you must specify the static size of each dimension between each pair of brackets. i.e. [{size}]. For more information about declaring arrays refer to Array Variable Assignments.
{identifier} may be between 1 and 4096 characters in length, must start with a letter, and may not contain spaces. Recommended characters are 0-9, a-z, A-Z and _ (underscore).
The Float command declares Float variables. A Float is a 32-bit IEEE floating point number. The Float data type has Mantissa precision 7, 10-38 to 1038.
Multiple variables may be declared on one command line, with their names separated from each other by spaces.
Procedure DoTest
Float fMyVar
Move 3.9999 To fMyVar
End_Procedure
This example declares one variable of type Float, named fMyVar, and initializes it.
Float[] fPrecisionValues
This example declares 1 dynamic array variable, named fPrecisionValues, containing an undefined number of elements of type Float.
Float[5] fPrecisionValues
This example declares 1 static array variable, named fPrecisionValues, containing 5 of elements of type Float.
Float[][3] fPrecisionValues
This example creates a two-dimensional dynamic array variable named fPrecisionValues, containing an undefined number of elements of type Float. Conceptually, this represents a rectangular array with an undefined number of rows, each of 3 columns.
You can declare dynamic multi-dimensional arrays where all dimensions are dynamic; these are called jagged arrays.
Compatible with the IEEE specification.
If you need to define a global Float variable, you should use the global_variable command to do so.
