DoubleConverter

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

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

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)
