Double Statement

Declares variables of type Double. (8 byte double precision number).

Syntax
Double varName [(subscripts)] [, varName [(subscripts)]...]

Parameters

varName

Specify the variable name which the user wants to declare as type Double.

Maximum element number of the array variable

Optional. Dimensions of an array variable; up to 3 dimensions may be declared. The subscripts syntax is as follows

(ubound1, [ubound2], [ubound3])

ubound1, ubound2, ubound3 each specify the maximum upper bound for the associated dimension. The elements in each dimension of an array are numbered from 0 and the available number of array elements is the upper bound value + 1. When specifying the upper bound value, make sure the number of total elements is within the range shown below:

• Local variable: 2,000
• Global Preserve variable: 4,000
• Global variable and module variable: 100,000

Double Statement Example
The following example shows a simple program which declares some variables using Double.

Function doubletest
  Double var1
  Double A(10)         'Single dimension array of double
  Double B(10, 10)     'Two dimension array of double
  Double C(5, 5, 5)    'Three dimension array of double
  Double arrayvar(10)
  Integer i
  Print "Please enter a Number:"
  Input var1
  Print "The variable var1 = ", var1
  For i = 1 To 5
    Print "Please enter a Number:"
    Input arrayvar(i)
    Print "Value Entered was ", arrayvar(i)
  Next i
Fend
