NAME

Data::Object::Number - A Number Object for Perl 5

VERSION

version 0.11

SYNOPSIS

use Data::Object::Number;

my $number = Data::Object::Number->new(1_000_000);

DESCRIPTION

Data::Object::Number provides common methods for operating on Perl 5 numeric data. 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). Users of numbers should be aware of the methods that modify the number itself as opposed to returning a new number. Unless stated, it may be safe to assume that the following methods copy, modify and return new numbers based on their function.

METHODS

abs

# given 12

$number->abs; # 12

$number = -12;
$number->abs; # 12

The abs method returns the absolute value of the number. This method returns a Data::Object::Number object.

atan2

# given 1

$number->atan2(1); # 0.785398163397448

The atan2 method returns the arctangent of Y/X in the range -PI to PI This method returns a Data::Object::Float object.

cos

# given 12

$number->cos; # 0.843853958732492

The cos method computes the cosine of the number (expressed in radians). This method returns a Data::Object::Float object.

decr

# given 123456789

$number->decr; # 123456788

The decr method returns the numeric number decremented by 1. This method returns a data type object to be determined after execution.

exp

# given 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 number. This method returns a Data::Object::Float object.

hex

# given 175

$number->hex; # 0xaf

The hex method returns a hex string representing the value of the number. This method returns a Data::Object::String object.

incr

# given 123456789

$number->incr; # 123456790

The incr method returns the numeric number incremented by 1. This method returns a data type object to be determined after execution.

int

# given 12.5

$number->int; # 12

The int method returns the integer portion of the number. Do not use this method for rounding. This method returns a Data::Object::Number object.

log

# given 12345

$number->log; # 9.42100640177928

The log method returns the natural logarithm (base e) of the number. This method returns a Data::Object::Float object.

mod

# given 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 number divided by the argment. This method returns a Data::Object::Number object.

neg

# given 12345

$number->neg; # -12345

The neg method returns a negative version of the number. This method returns a Data::Object::Integer object.

pow

# given 12345

$number->pow(3); # 1881365963625

The pow method returns a number, the result of a math operation, which is the number to the power of the argument. This method returns a Data::Object::Number object.

sin

# given 12345

$number->sin; # -0.993771636455681

The sin method returns the sine of the number (expressed in radians). This method returns a data type object to be determined after execution.

sqrt

# given 12345

$number->sqrt; # 111.108055513541

The sqrt method returns the positive square root of the number. This method returns a data type object to be determined after execution.
