Signature: floatToInt(x: float) -> Result<int, Error>

Description: Checked truncation toward zero: Success(n) when x is finite and inside the int range, Error for NaN, infinities and out-of-range magnitudes.

Parameters

• x (float): The float to truncate

Returns: Result<int, Error>

Example

fn describe(x) = match floatToInt(x) {
    Success { value } => toString(value)
    Error { message } => message
}
print("${describe(-2.9)}\n${describe(sqrt(-1.0))}")

describe x = match floatToInt x
    Success value => toString value
    Error message => message
print "${describe (-2.9)}\n${describe (sqrt (-1.0))}"
