To Integer (String)

The To Integer (String) node in Magick converts a string representation of an integer into an actual integer value. This is useful when you have a number stored as text and need to perform mathematical operations or comparisons on it.

​
Inputs

  • a (string, default: ""): The string to convert to an integer.

​
Outputs

  • result (integer): The integer value parsed from the input string.

​
Configuration

This node has no configuration options.

​
Usage

  1. Connect a node that provides a string output to the a input of the To Integer (String) node.
  2. The node will parse the string and output the corresponding integer value from the result output.
  3. Connect the result output to other nodes that expect an integer input, such as math operation nodes or comparison nodes.

​
Example

Let’s say you have a spell that retrieves a user’s age as a string from a form submission. To perform calculations or comparisons based on the age, you need to convert it to an integer:

  1. Connect the output of the form submission node to the a input of the To Integer (String) node.
  2. Connect the result output of the To Integer (String) node to a comparison node, such as the Greater Than node.
  3. Set the other input of the Greater Than node to a fixed integer value, like 18.
  4. The Greater Than node will now output true or false depending on whether the user’s age is over 18.

​
Best Practices

  • Ensure that the input string represents a valid integer. If the string contains non-numeric characters or is empty, the node will output 0.
  • Be aware of the integer range limitations in JavaScript. The safe integer range is from -(2^53 - 1) to (2^53 - 1). Converting strings outside this range may result in loss of precision.

​
Common Issues

  • Passing a string that contains non-numeric characters will result in an output of 0. Make sure to validate and sanitize the input string if needed.
  • Leading or trailing whitespace in the input string is automatically trimmed before parsing the integer.

By using the To Integer (String) node, you can easily convert string-based numbers into actual integer values, enabling mathematical operations and comparisons in your Magick spells.
