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 Operations with NEGATIVE_INFINITY as an operand may result in NEGATIVE_INFINITY, POSITIVE_INFINITY or NaN. For detailed information, see ...
If this constant is converted to an Int, e.g. through Std.int(), the result is unspecified.
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

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 smallest Int 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.
TODO: need spec
Returns the trigonometric cosine of v
.
The unit of v
is radians.
If v
is NaN or infinite, the result is NaN.
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.
Returns the largest Int 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.
TODO: need spec
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.
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.
Returns the natural logarithm of v
.
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.
This is the inverse operation of exp, i.e. log(exp(v)) == v always holds.
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.
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.
Rounds v
to the nearest Int value.
If v is outside of the signed Int32 range, or is NaN, NEGATIVE_INFINITY or POSITIVE_INFINITY, the result is unspecified.
TODO: need spec
Returns the trigonometric sine of v
.
The unit of v
is radians.
If v
is NaN or infinite, the result is NaN.
Returns the square root of v
.
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 0.0.
