Using the Fields Control

The Fields control allows you to change input and output field types. You can change field types from within this control by clicking the drop-down arrow in the Type column and selecting from the list, which includes these options:

boolean

A logical type with two values: true and false. Boolean variables can be used in conditional statements to control flow. The code sample, below, shows a Boolean expression:

if(x && y)
     z=1;
  else if(x)
     z=2;
  else if(y)
     z=3;
  else
     z=4;

double

A numeric data type that contains both negative and positive double precision numbers between 2^-1074 and (2-2^-52)×2¹⁰²³. In E notation, the range of values is -1.79769313486232E+308 to 1.79769313486232E+308.

float

A numeric data type that contains both negative and positive single precision numbers between 2^-149 and (2-2²³)×2¹²⁷. In E notation, the range of values -3.402823E+38 to 3.402823E+38.

integer

A numeric data type that contains both negative and positive whole numbers between -2³¹ (-2,147,483,648) and 2³¹-1 (2,147,483,647).

long

A numeric data type that contains both negative and positive whole numbers between -2⁶³ (-9,223,372,036,854,775,808) and 2⁶³-1 (9,223,372,036,854,775,807).
