SPVM::IO - IO Library
FUNCTIONS
E
sub E : double ()
The double value that is closer than any other to e, the base of the natural logarithms.
PI
sub PI : double ()
The double value that is closer than any other to pi, the ratio of the circumference of a circle to its diameter.
sin
sub sin : double ($x : double)
Returns the trigonometric sine of an angle. Special cases:
=item* If the argument is NaN or an infinity, then the result is NaN.
=item* If the argument is zero, then the result is a zero with the same sign as the argument.
The computed result must be within 1 ulp of the exact result. Results must be semi-monotonic.
Parameters:
$x - an angle, in radians.
Returns:
the sine of the argument.
cos
sub cos : double ($x : double)
Returns the trigonometric cosine of an angle. Special cases:
=item* If the argument is NaN or an infinity, then the result is NaN.
The computed result must be within 1 ulp of the exact result. Results must be semi-monotonic.
Parameters:
$x - an angle, in radians.
Returns:
the cosine of the argument.
tan
sub tan : double ($x : double)
Returns the trigonometric tangent of an angle. Special cases:
=item* If the argument is NaN or an infinity, then the result is NaN.
=item* If the argument is zero, then the result is a zero with the same sign as the argument.
The computed result must be within 1 ulp of the exact result. Results must be semi-monotonic.
Parameters:
$x - an angle, in radians.
Returns:
the tangent of the argument.
asin
sub asin : double ($x : double)
Returns the arc sine of a value; the returned angle is in the range -pi/2 through pi/2. Special cases:
If the argument is NaN or its absolute value is greater than 1, then the result is NaN.
If the argument is zero, then the result is a zero with the same sign as the argument.
The computed result must be within 1 ulp of the exact result. Results must be semi-monotonic.
Parameters:
$x - the value whose arc sine is to be returned.
Returns:
the arc sine of the argument.
acos
sub acos : double ($x : double)
Returns the arc cosine of a value; the returned angle is in the range 0.0 through pi. Special case:
If the argument is NaN or its absolute value is greater than 1, then the result is NaN.
The computed result must be within 1 ulp of the exact result. Results must be semi-monotonic.
Parameters:
$x - the value whose arc cosine is to be returned.
Returns:
the arc cosine of the argument.
atan
sub atan : double ($x : double)
Returns the arc tangent of a value; the returned angle is in the range -pi/2 through pi/2. Special cases:
If the argument is NaN, then the result is NaN.
If the argument is zero, then the result is a zero with the same sign as the argument.
The computed result must be within 1 ulp of the exact result. Results must be semi-monotonic.
Parameters:
$x - the value whose arc tangent is to be returned.
Returns:
the arc tangent of the argument.
erf
native sub erf : double ($x : double);
erfc
native sub erfc : double ($x : double);
