This class defines mathematical functions and constants.

### Static variables

`staticread onlyNEGATIVE_INFINITY:Float`

*Available on Linux, Android, Windows, iOS, Flash, Neko, macOS*

A special Float constant which denotes negative infinity.

For example, this is the result of -1.0 / 0.0.

Operations with NEGATIVE_INFINITY as an operand may result in NEGATIVE_INFINITY, POSITIVE_INFINITY or NaN.

If this constant is converted to an Int, e.g. through Std.int(), the result is unspecified.

*Available on Linux, Android, Windows, iOS, Flash, Neko, macOS*

A special Float constant which denotes an invalid number.

NaN stands for "Not a Number". It occurs when a mathematically incorrect operation is executed, such as taking the square root of a negative number: Math.sqrt(-1).

All further operations with NaN as an operand will result in NaN.

If this constant is converted to an Int, e.g. through Std.int(), the result is unspecified.

In order to test if a value is NaN, you should use Math.isNaN() function.

@php In PHP versions prior to 5.3.1 VC 9 there may be unexpected results when performing arithmetic operations with NaN on Windows, see [https://bugs.php.net/bug.php?id=42143]

Represents the ratio of the circumference of a circle to its diameter,
specified by the constant, π. `PI`

is approximately 3.141592653589793.

`staticread onlyPOSITIVE_INFINITY:Float`

*Available on Linux, Android, Windows, iOS, Flash, Neko, macOS*

A special Float constant which denotes negative infinity.

For example, this is the result of 1.0 / 0.0.

Operations with POSITIVE_INFINITY as an operand may result in NEGATIVE_INFINITY, POSITIVE_INFINITY or NaN.

If this constant is converted to an Int, e.g. through Std.int(), the result is unspecified.

### Static methods

Returns the absolute value of `v`

.

If `v`

is positive or 0, the result is unchanged. Otherwise the result
is -`v`

.

If `v`

is NEGATIVE_INFINITY or POSITIVE_INFINITY, the result is
POSITIVE_INFINITY.

If `v`

is NaN, the result is NaN.

Returns the trigonometric arc cosine of the specified angle `v`

,
in radians.

If `v`

is NaN or infinite, the result is NaN.

*Available on Linux, Android, Windows, iOS, Flash, macOS*

Returns the trigonometric arc of the specified angle `v`

, in radians.

If `v`

is NaN or infinite, the result is NaN.

*Available on Linux, Android, Windows, iOS, Flash, macOS*

Returns the trigonometric arc tangent of the specified angle `v`

,
in radians.

If `v`

is NaN or infinite, the result is NaN.

`staticatan2 (y:Float, x:Float):Float`

*Available on Linux, Android, Windows, iOS, Flash, macOS*

Returns the trigonometric arc tangent whose tangent is the quotient of two specified numbers, in radians.

If parameter `x`

or `y`

is NaN, NEGATIVE_INFINITY or POSITIVE_INFINITY,
the result is NaN.

Returns the smallest integer value that is not less than `v`

.

If `v`

is outside of the signed Int32 range, or is NaN, NEGATIVE_INFINITY
or POSITIVE_INFINITY, the result is unspecified.

Returns the trigonometric cosine of the specified angle `v`

, in radians.

If `v`

is NaN or infinite, the result is NaN.

*Available on Linux, Android, Windows, iOS, Flash, macOS*

Returns Euler's number, raised to the power of `v`

.

exp(1.0) is approximately 2.718281828459.

If `v`

is POSITIVE_INFINITY, the result is POSITIVE_INFINITY.
If `v`

is NEGATIVE_INFINITY, the result is 0.0.
If `v`

is NaN, the result is NaN.

*Available on Linux, Android, Windows, iOS, Flash, macOS*

Returns the smallest integer value that is not less than `v`

, as a Float.

If `v`

is is NaN, NEGATIVE_INFINITY or POSITIVE_INFINITY,
the result is unspecified.

*Available on Linux, Android, Windows, iOS, Flash, macOS*

Returns the largest integer value that is not greater than `v`

, as a Float.

If `v`

is is NaN, NEGATIVE_INFINITY or POSITIVE_INFINITY,
the result is unspecified.

Returns the largest integer value that is not greater than `v`

.

If `v`

is outside of the signed Int32 range, or is NaN, NEGATIVE_INFINITY
or POSITIVE_INFINITY, the result is unspecified.

*Available on Linux, Android, Windows, iOS, Flash, macOS*

Rounds `v`

to the nearest integer value, as a Float.

If `v`

is is NaN, NEGATIVE_INFINITY or POSITIVE_INFINITY,
the result is unspecified.

*Available on Linux, Android, Windows, iOS, Flash, Neko, macOS*

Tells if `f`

is a finite number.

If `f`

is POSITIVE_INFINITY, NEGATIVE_INFINITY or NaN, the result
is false, otherwise the result is true.

*Available on Linux, Android, Windows, iOS, Flash, Neko, macOS*

Tells if `f`

is not a valid number.

If `f`

is NaN, the result is true, otherwise the result is false.
In particular, both POSITIVE_INFINITY and NEGATIVE_INFINITY are
not considered NaN.

*Available on Linux, Android, Windows, iOS, Flash, HTML5, macOS*

Returns the natural logarithm of `v`

.

This is the mathematical inverse operation of exp,
i.e. `log(exp(v)) == v`

always holds.

If `v`

is negative (including NEGATIVE_INFINITY) or NaN, the result
is NaN.
If `v`

is POSITIVE_INFINITY, the result is POSITIVE_INFINITY.
If `v`

is 0.0, the result is NEGATIVE_INFINITY.

`staticmax (a:Float, b:Float):Float`

*Available on Linux, Android, Windows, iOS, Flash, macOS*

Returns the greater of values `a`

and `b`

.

If `a`

or `b`

are NaN, the result is NaN.
If `a`

or `b`

are POSITIVE_INFINITY, the result is POSITIVE_INFINITY.
If `a`

and `b`

are NEGATIVE_INFINITY, the result is NEGATIVE_INFINITY.

`staticmin (a:Float, b:Float):Float`

*Available on Linux, Android, Windows, iOS, Flash, macOS*

Returns the smaller of values `a`

and `b`

.

If `a`

or `b`

are NaN, the result is NaN.
If `a`

or `b`

are NEGATIVE_INFINITY, the result is NEGATIVE_INFINITY.
If `a`

and `b`

are POSITIVE_INFINITY, the result is POSITIVE_INFINITY.

*Available on Linux, Android, Windows, iOS, Flash, HTML5, macOS*

Returns a specified base `v`

raised to the specified power `exp`

.

Rounds `v`

to the nearest integer value.

If `v`

is outside of the signed Int32 range, or is NaN, NEGATIVE_INFINITY
or POSITIVE_INFINITY, the result is unspecified.

Returns the trigonometric sine of the specified angle `v`

, in radians.

If `v`

is NaN or infinite, the result is NaN.
