Static variables
staticread onlyNEGATIVE_INFINITY:Float = cs.system.Double.NegativeInfinity
Available on cs, cpp, flash, php, macro, hl, neko, java, python
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.
staticread onlyNaN:Float = cs.system.Double.NaN
Available on cs, cpp, flash, php, macro, hl, neko, java, python
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.
staticread onlyPI:Float = cs.system.Math.PI
Available on cs, cpp, flash, php, js, macro, hl, neko, java, python
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 = cs.system.Double.PositiveInfinity
Available on cs, cpp, flash, php, macro, hl, neko, java, python
A special Float constant which denotes positive 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
staticabs(v:Float):Float
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.
staticacos(v:Float):Float
Returns the trigonometric arc cosine of the specified angle v,
in radians.
If v is NaN or infinite, the result is NaN.
staticasin(v:Float):Float
Returns the trigonometric arc of the specified angle v, in radians.
If v is NaN or infinite, the result is NaN.
staticatan(v:Float):Float
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
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.
staticceil(v:Float):Int
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.
staticcos(v:Float):Float
Returns the trigonometric cosine of the specified angle v, in radians.
If v is NaN or infinite, the result is NaN.
staticexp(v:Float):Float
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.
staticfceil(v:Float):Float
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.
staticffloor(v:Float):Float
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.
staticfloor(v:Float):Int
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.
staticfround(v:Float):Float
Rounds v to the nearest integer value, as a Float.
Ties are rounded up, so that 0.5 becomes 1 and -0.5 becomes 0.
If v is is NaN, NEGATIVE_INFINITY or POSITIVE_INFINITY,
the result is unspecified.
staticlog(v:Float):Float
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
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
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.
staticrandom():Float
Returns a pseudo-random number which is greater than or equal to 0.0, and less than 1.0.
staticround(v:Float):Int
Rounds v to the nearest integer value.
Ties are rounded up, so that 0.5 becomes 1 and -0.5 becomes 0.
If v is outside of the signed Int32 range, or is NaN, NEGATIVE_INFINITY
or POSITIVE_INFINITY, the result is unspecified.
staticsin(v:Float):Float
Returns the trigonometric sine of the specified angle v, in radians.
If v is NaN or infinite, the result is NaN.
