pjs.math

This API is a tag function that is used to evaluate a math expression specified as a tagged template literal. Math expression evaluation is performed by the mathjs library. Math evaluation supports precise decimal values, and arithmetic results are returned as precise decimal. See the mathjs documentation for syntax.

This API is typically used in applications that have been transformed from RPG code. Profound Logic’s RPG to JavaScript converter uses this API to assist in transformation of math expressions involving large decimal values.

Parameters

Math expression string: A template literal string containing a math expression and optional placeholder values.

Example

  pjs.define("num1", { type: "packed", length: 19, decimals: 4, precise: true, initValue: "222222222222222.3333" });
  pjs.define("num2", { type: "packed", length: 19, decimals: 4, precise: true, initValue: "444444444444444.2222" });
  pjs.define("result", { type: "packed", length: 19, decimals: 4, precise: true });

  result = pjs.math`${num1} + ${num2}`;
  console.log(String(result)); // Output: 666666666666666.5555
