lroundf

Rounds it's argument to the nearest integer value, rounding away from zero, regardless of the current rounding direction.

If x is infinite or float.NAN, or if the rounded value is outside the range of the return type, the numeric result is unspecified.

A domain error may occur if the magnitude of x is too large.

Example: Round float to long:

public static int main (string[] args) {
	// Output:
	//  ``lroundf (0.3f) =  0f``
	//  ``lroundf (0.4f) =  0f``
	//  ``lroundf (0.5f) =  1f``
	//  ``lroundf (0.6f) =  1f``

	print ("lroundf (%.1lff) =  %lif\n", 0.3f, Math.lroundf (0.3f));
	print ("lroundf (%.1lff) =  %lif\n", 0.4f, Math.lroundf (0.4f));
	print ("lroundf (%.1lff) =  %lif\n", 0.5f, Math.lroundf (0.5f));
	print ("lroundf (%.1lff) =  %lif\n", 0.6f, Math.lroundf (0.6f));

	return 0;
}
