Number

Safe numeric operations. Parsing returns Result instead of NaN.

Functions

Function	Signature	Description
Number.parse	string -> Result<number, ParseError>	Strict parse (no partial, no NaN)
Number.clamp	number, number, number -> number	Clamp between min and max
Number.isFinite	number -> boolean	Check if finite
Number.isInteger	number -> boolean	Check if integer
Number.toFixed	number, number -> string	Format with fixed decimals
Number.toString	number -> string	Convert to string

Examples

// Safe parsing - no more NaN surprises
const result = "42" |> Number.parse
// Ok(42)

const bad = "not a number" |> Number.parse
// Err(ParseError)

// Must handle the Result
match Number.parse(input) {
  Ok(n)  -> processNumber(n),
  Err(_) -> showError("Invalid number"),
}

// Clamp to range
const score = rawScore |> Number.clamp(0, 100)
