# Number

Wrappers for basic numerical values.

The Number object has been split into one class per basic WebAssembly type as well. Unlike in JavaScript, these classes cannot have actual instances, hence it works a bit different than JavaScript's (MDN).

# Integers

The name Number below stands for one of the wrappers I8, I16, I32, I64, U8, U16, U32 or U64 representing their respective basic integer type T.

# Static members

  • const MIN_VALUE: T
    

    The smallest representable value of the respective basic type. Differs from floating point values where it is the smallest representable positive value.

  • const MAX_VALUE: T
    

    The largest representable value of the respective basic type.

  • function parseInt(value: string, radix?: i32): T
    

    Parses a string to a value of the respective basic type.

# Instance members

  • function toString(radix?: i32): string
    
    Returns the respective basic value converted to a string. The radix parameter is not supported yet.

# Floats

The name Number below stands for one of the wrappers F32 or F64 representing their respective basic floating point type T.

# Static members

  • const EPSILON: T
    

    The difference between 1.0 and the smallest number larger than 1.0.

  • const MAX_VALUE: T
    

    The largest representable positive value by the respective basic type.

  • const MIN_VALUE: T
    

    The smallest representable positive value by the respective basic type.

  • const MAX_SAFE_INTEGER: T
    

    The largest safe integer representable by the respective basic type.

  • const MIN_SAFE_INTEGER: T
    

    The smallest safe integer representable by the respective basic type.

  • const POSITIVE_INFINITY: T
    

    Positive infinity of the respective basic type.

  • const NEGATIVE_INFINITY: T
    

    Negative infinity of the respective basic type.

  • const NaN: T
    

    NaN (Not A Number) of the respective basic type.

  • function isNan(value: T): bool
    

    Tests if the value is NaN.

  • function isFinite(value: T): bool
    

    Tests if the value is finite, that is not NaN , POSITIVE_INFINITY or NEGATIVE_INFINITY.

  • function isInteger(value: T): bool
    

    Tests if the value is an integer.

  • function isSafeInteger(value: T): bool
    

    Tests if the value is a safe integer.

  • function parseInt(value: string, radix?: i32): T
    

    Parses a string to an integer value of the respective basic type.

  • function parseFloat(value: string): T
    

    Parses a string to a float value of the respective basic type.

# Instance members

  • function toString(radix?: i32): string
    
    Returns the respective basic value converted to a string.
