# FUNCTIONS

## print

Print string to stdout.

``  sub print : void (\$string : string);``

## warn

## 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.
