fromBase

Description

Converts a string representation of a number in a given base into its numeric value.

For example, "101" in base 2 becomes 5 in base 10.

Syntax

Like many functions in DataPrime, fromBase supports two notations, function and method. These interchangeable forms allow flexibility in how you structure expressions.

Function notation

fromBase(string: string, radix: number): number

Method notation

(string: string).fromBase(radix: number): number

Arguments

Name	Type	Required	Description
string	string	true	The string containing the number
radix	number	true	The base of the string representation (e.g. hexadecimal is base 16)

Example

Use case: Parse a hexadecimal string

Convert a hexadecimal string to a numeric value so it can be used in calculations.

Example data

{
    "hex_value": "FF00FF"
}

Example query

Function notation

create num_value from fromBase(hex_value, 16)

Method notation

create num_value from hex_value.fromBase(16)

Example output

{
    "hex_value": "FF00FF",
    "num_value": 16711935
}
