toDecimalNumber

Checks if the string can be parsed as a decimal number (Double).

This property uses toDoubleOrNull to safely attempt the conversion. It returns true if the string represents a valid floating-point number, and false otherwise.

Examples:

• "123.45".toDecimalNumber -> true

• "-50".toDecimalNumber -> true

• "abc".toDecimalNumber -> false

• "".toDecimalNumber -> false
