Bubblegum::Object::Number - Common Methods for Operating on Numbers
version 0.11
use Bubblegum; my $number = 123456789; say $number->incr; # 123456790
Number methods work on data that meets the criteria for being a number. A number holds and manipulates an arbitrary sequence of bytes, typically representing numberic characters (0-9). It is not necessary to use this module as it is loaded automatically by the Bubblegum class.
my $number = 12; $number->abs; # 12 $number = -12; $number->abs; # 12
The abs method returns the absolute value of the subject.
my $number = 1; $number->atan2(1); # 0.785398163397448
The atan2 method returns the arctangent of Y/X in the range -PI to PI
my $number = 12; $number->cos; # 0.843853958732492
The cos method computes the cosine of the subject (expressed in radians).
my $number = 123456789; $number->decr; # 123456788
The decr method returns the numeric subject decremented by 1.
my $number = 0; $number->exp; # 1 $number = 1; $number->exp; # 2.71828182845905 $number = 1.5; $number->exp; # 4.48168907033806
The exp method returns e (the natural logarithm base) to the power of the subject.
my $number = 175; $number->hex; # 0xaf
The hex method returns a hex string representing the value of the subject.
my $number = 123456789; $number->incr; # 123456790
The incr method returns the numeric subject incremented by 1.
my $number = 12.5; $number->int; # 12
The int method returns the integer portion of the subject. Do not use this method for rounding.
my $number = 12345; $number->log; # 9.42100640177928
The log method returns the natural logarithm (base e) of the subject.
my $number = 12; $number->mod(1); # 0 $number->mod(2); # 0 $number->mod(3); # 0 $number->mod(4); # 0 $number->mod(5); # 2
The mod method returns the division remainder of the subject divided by the argment.
my $number = 12345; $number->neg; # -12345
The neg method returns a negative version of the subject.
my $number = 12345; $number->pow(3); # 1881365963625
The pow method returns a number, the result of a math operation, which is the subject to the power of the argument.
my $number = 12345; $number->sin; # -0.993771636455681
The sin method returns the sine of the subject (expressed in radians).
my $number = 12345; $number->sqrt; # 111.108055513541
The sqrt method returns the positive square root of the subject.
my $int = 1; $int->to_array; # [1]
The to_array method is used for coercion and simply returns an array reference where the first element contains the subject.
my $int = 1; $int->to_code; # sub { 1 }
The to_code method is used for coercion and simply returns a code reference which always returns the subject when called.
my $int = 1; $int->to_hash; # { 1 => 1 }
The to_hash method is used for coercion and simply returns a hash reference with a single key and value, having the key and value both contain the subject.
my $int = 1; $int->to_integer; # 1
The to_integer method is used for coercion and simply returns the subject.
my $int = 1; $int->to_string; # '1'
The to_string method is used for coercion and simply returns the stringified version of the subject.
