Compute Expression

syntax

The computeExpression function has the following syntax:

function computeExpression(
  formula: string,
  options?: {
    parameters?: Parameters;
    decimalPlaces?: number;
    useThousandSeparator?: boolean;
  },
): string;

function computeExpression(
  formula: string,
  options?: {
    parameters?: Parameters;
    decimalPlaces?: number;
    useThousandSeparator?: boolean;
  },
): string;

Where:

formula is a string that represents the mathematical expression to be evaluated.
options is an optional object that may include:
- parameters: An object of key-value pairs where the key is the variable name in the formula, and the value is the number to substitute for that variable.
- decimalPlaces: The number of decimal places to include in the result. If not provided, the result will include all decimal places.
- useThousandSeparator: A boolean indicating whether to include a thousand separator in the result. If true, the result will include a thousand separator.

Basic Usage

computeExpression(formula: string): Evaluates a mathematical expression represented as a string.

computeExpression("0.1+0.2"); // returns "0.3"
// or
const object = { x: 0.1, y: 0.2 };
computeExpression(`${object.x}+${object.y}`); // returns "0.3"

computeExpression("0.1+0.2"); // returns "0.3"
// or
const object = { x: 0.1, y: 0.2 };
computeExpression(`${object.x}+${object.y}`); // returns "0.3"

computeExpression(formula: string, {parameters:Parameters}): Evaluates an expression with parameters.

const parameters = { x: 0.1, y: 0.2 };
computeExpression("x+y", {
  parameters,
}); // returns "0.3"

const parameters = { x: 0.1, y: 0.2 };
computeExpression("x+y", {
  parameters,
}); // returns "0.3"

computeExpression(formula: string, {decimalPlaces: number}): Evaluates an expression with decimal places.

computeExpression("0.1+0.2", {
  decimalPlaces: 2,
}); // returns "0.30"

computeExpression("0.113+0.223", {
  decimalPlaces: 2,
}); // returns "0.34"

computeExpression("0.1+0.2", {
  decimalPlaces: 2,
}); // returns "0.30"

computeExpression("0.113+0.223", {
  decimalPlaces: 2,
}); // returns "0.34"

computeExpression(formula: string, {useThousandSeparator: boolean}): Evaluates an expression with thousand separator.

computeExpression("1111.1+2222.2", {
  useThousandSeparator: true,
}); // returns "3,333.3"

computeExpression("1111.1+2222.2", {
  useThousandSeparator: true,
}); // returns "3,333.3"

computeExpression(formula: string, {parameters: Parameters, decimalPlaces: number}): Evaluates an expression with parameters and decimal places.

computeExpression("x+y", {
  parameters: { x: 1111.113, y: 2222.223 },
  decimalPlaces: 2,
}); // returns "3333.34"

computeExpression("x+y", {
  parameters: { x: 1111.113, y: 2222.223 },
  decimalPlaces: 2,
}); // returns "3333.34"

computeExpression(formula: string, {parameters: Parameters, useThousandSeparator: boolean}): Evaluates an expression with parameters and thousand separator.

computeExpression("1111.113+2222.223", {
  decimalPlaces: 2,
  useThousandSeparator: true,
}); // returns "3,333.34"

computeExpression("1111.113+2222.223", {
  decimalPlaces: 2,
  useThousandSeparator: true,
}); // returns "3,333.34"

computeExpression(formula: string, {parameters: Parameters, decimalPlaces: number, useThousandSeparator: boolean}): Evaluates an expression with parameters, decimal places, and thousand separator.

computeExpression("1111.113+2222.223", {
  parameters: { x: 1111.113, y: 2222.223 },
  decimalPlaces: 2,
  useThousandSeparator: true,
}); // returns "3,333.34"

computeExpression("1111.113+2222.223", {
  parameters: { x: 1111.113, y: 2222.223 },
  decimalPlaces: 2,
  useThousandSeparator: true,
}); // returns "3,333.34"
