TODO

abs

The absolute value of the number.

:::dart
-123.abs // 123

ceil

TODO

cos

The cosine of the number.

floor

TODO

isNan

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.

sin

The sine of the number.

sqrt

The square root of the number. Returns nan if the number is negative.

- operator

Negates the number.

:::dart
var a = 123
-a // -123

-(other), +(other), /(other), *(other) operators

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.

%(denominator) operator

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

It is a runtime error if denominator is not a number.

<(other), >(other), <=(other), >=(other) operators

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.

~ operator

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.

&(other) operator

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.

|(other) operator

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.
