sqrtf

Returns the non-negative square root of x.

It fails and sets GLib.errno to EDOM , if x is negative.

Example: Square root (float):

public static int main (string[] args) {
	//                 /----
	// sqrtf (4f) =  \/  4   = 2
	//

	// Output: ``sqrtf (4.0f) = 2.000000f``
	float res = Math.sqrtf (4.0f);
	print ("sqrtf (4.0f) = %lff\n", res);
	return 0;
}

valac --pkg glib-2.0 -X -lm GLib.Math.sqrtf.vala

Parameters:

x	A numeric value.
