Attempts to parse `value`

as a decimal literal and return it as an instance of
`Num`

. If the number cannot be parsed `null`

will be returned.

It is a runtime error if `value`

is not a string.

The value of π.

The absolute value of the number.

System.print( (-123).abs ) 123

The arc cosine of the number.

The arc sine of the number.

The arc tangent of the number.

The arc tangent of the number when divided by `x`

, using the signs of the two
numbers to determine the quadrant of the result.

Rounds the number up to the nearest integer.

System.print(1.5.ceil) 2 System.print((-3.2).ceil) -3

The cosine of the number.

Rounds the number down to the nearest integer.

System.print(1.5.floor) 1 System.print((-3.2).floor) -4

Whether the number is positive or negative infinity or not.

System.print(99999.isInfinity) false System.print((1/0).isInfinity) true

Whether the number is an integer or has some fractional component.

System.print(2.isInteger) true System.print(2.3.isInteger) false

Whether the number is not a number. This is
`false`

for normal number values and infinities, and `true`

for the result of
`0/0`

, the square root of a negative number, etc.

The sine of the number.

The square root of the number. Returns `nan`

if the number is negative.

The tangent of the number.

Negates the number.

var a = 123 System.print(-a) -123

The usual arithmetic operators you know and love. All of them do 64-bit floating point arithmetic. It is a runtime error if the right-hand operand is not a number. Wren doesn’t roll with implicit conversions.

The floating-point remainder of this number divided by `denominator`

.

It is a runtime error if `denominator`

is not a number.

Compares this and `other`

, returning `true`

or `false`

based on how the numbers
are ordered. It is a runtime error if `other`

is not a number.

Performs *bitwise* negation on the number. The number is first converted to a
32-bit unsigned value, which will truncate any floating point value. The bits
of the result of that are then negated, yielding the result.

Performs bitwise and on the number. Both numbers are first converted to 32-bit
unsigned values. The result is then a 32-bit unsigned number where each bit is
`true`

only where the corresponding bits of both inputs were `true`

.

It is a runtime error if `other`

is not a number.

Performs bitwise or on the number. Both numbers are first converted to 32-bit
unsigned values. The result is then a 32-bit unsigned number where each bit is
`true`

only where the corresponding bits of both inputs were `true`

.

It is a runtime error if `other`

is not a number.

Creates a Range representing a consecutive range of numbers from the beginning number to the ending number.

var range = 1.2..3.4 System.print(range.min) 1.2 System.print(range.max) 3.4 System.print(range.isInclusive) true

Creates a Range representing a consecutive range of numbers from the beginning number to the ending number not including the ending number.

var range = 1.2...3.4 System.print(range.min) 1.2 System.print(range.max) 3.4 System.print(range.isInclusive) false
