The square root of x as a float or float64, correctly rounded. A negative argument gives NaN; sqrt(-0.0) is -0.0 and sqrt(infinity) is infinity.
assert(sqrt(9.0) == 3 && sqrt(cast(float64) 2) > 1.4142 && sqrt(0.0) == 0);
assert(isnan(sqrt(-1.0)));sqrt :: (x: float) -> floatSquare root.
Parameters
- x: float
- the value. Negative gives NaN.
Returns
- float
sqrt :: (x: float64) -> float64Square root.
Parameters
- x: float64
- the value. Negative gives NaN.
Returns
- float64
