Number

inherits Object final

A number is a 64 bit floating point number.

methods

• to_string() returns a String representing the number
• square_root() returns the square root of the number
• even?() returns true if the number is evenly divisible by 2
• floor() returns the nearest whole integer, searching lower numbers
• ceiling() returns the nearest whole integer, searching higher numbers
• power(n) returns number raised to the power of n

static methods

• parse() takes a string and parses it into a Number. Returns nil if the string couldn’t be parsed into a number.
• max(n, m) returns the maximum value between n and m or m if they are the same
• min(n, m) returns the minimum value between n and m or m if they are the same
• random([seed]) returns a random value between 0 and 1.0 - this is NOT suitable for cryptography. Optionally allows a seed to be specified. The seed should be able to fit into a 32 bit integer.

operators

• == compares the two objects to see if they’re the same instance
• - performs the mathmatical subtraction operation
• + performs the mathmatical addition operation
• * performs the mathmatical multiplication operation
• / performs the mathmatical division operation (floating point)
• % performs the mathmatical remainder operation (casts both operands to uint64_t)
• > performs the strict greater than comparision
• >= performs the greater than or equal to comparision
• < performs the strict less than comparision
• <= performs the less than or equal to comparision
• ~ bitwise negates the number
• << bitwise left shift the argument number of bits
• >> bitwise right shift the argument number of bits
• | bitwise inclusive or
• & bitwise and
• ^ bitwise exclusive or

All bitwise operations are performed as though the number is a signed 64 bit integer
