DoubleConverter

The DoubleConverter class allows you to convert arbitrary values into doubles using extended conversion rules.

Description

The DoubleConverter class allows you to convert arbitrary values into doubles using the following extended conversion rules:

  • Strings are converted to double values

  • DateTime: total number of milliseconds since unix epoch

  • Boolean: 1 for true and 0 for false

See toDoubleWithDefault

public static toDouble(value: any): number

toDoubleWithDefault

Converts value into integer or returns default value when the conversion is not possible.

public static toDoubleWithDefault(value: any, defaultValue: number = 0): number

  • value: any - value to convert.
  • defaultValue: number - default value.
  • returns: number - double value or default when the conversion is not supported.

toNullableDouble

Converts a value into a double or returns null when the conversion is not possible.

public static toNullableDouble(value: any): number

  • value: any - value to convert.
  • returns: number - double value or null when the conversion is not supported.

Examples

let value1 = DoubleConverter.toNullableDouble("ABC")     // Returns null
let value2 = DoubleConverter.toNullableDouble("123.456") // Returns 123.456
let value3 = DoubleConverter.toNullableDouble(True)      // Returns 1
let value4 = DoubleConverter.toNullableDouble(new Date()) // Returns current milliseconds (E.g. 1619812281454)
