  $number->exp; # 4.48168907033806

ge

  ge(Any $arg1) : Num

The ge method returns true if the argument provided is greater-than or equal-to the value represented by the object.

ge example #1

  my $number = Data::Object::Number->new(0);

  $number->ge(0); # 1

gt

  gt(Any $arg1) : Num

The gt method performs a numeric greater-than comparison.

gt example #1

  my $number = Data::Object::Number->new(99);

  $number->gt(50); # 1

hex

  hex() : Str

The hex method returns a hex string representing the value of the number.

hex example #1

  my $number = Data::Object::Number->new(175);

  $number->hex; # 0xaf

incr

  incr(Num $arg1) : Num

The incr method returns the numeric number incremented by 1.

incr example #1

  my $number = Data::Object::Number->new(123456789);

  $number->incr; # 123456790

int

  int() : Num

The int method returns the integer portion of the number. Do not use this method for rounding.

int example #1

  my $number = Data::Object::Number->new(12.5);

  $number->int; # 12

le

  le(Any $arg1) : Num

The le method returns true if the argument provided is less-than or equal-to the value represented by the object.

le example #1

  my $number = Data::Object::Number->new(0);

  $number->le(-1); # 0

log

  log() : Num

The log method returns the natural logarithm (base e) of the number.

log example #1

  my $number = Data::Object::Number->new(12345);

  $number->log; # 9.42100640177928

lt

  lt(Any $arg1) : Num

The lt method performs a numeric less-than comparison.

lt example #1

  my $number = Data::Object::Number->new(86);

  $number->lt(88); # 1

mod

  mod() : Num

The mod method returns the division remainder of the number divided by the argment.

  $number->ne(100); # 1

neg

  neg() : Num

The neg method returns a negative version of the number.

neg example #1

  my $number = Data::Object::Number->new(12345);

  $number->neg; # -12345

pow

  pow() : Num

The pow method returns a number, the result of a math operation, which is the number to the power of the argument.

pow example #1

  my $number = Data::Object::Number->new(12345);

  $number->pow(3); # 1881365963625

sin

  sin() : Num

The sin method returns the sine of the number (expressed in radians).

sin example #1

  my $number = Data::Object::Number->new(12345);

  $number->sin; # -0.993771636455681

sqrt

  sqrt(Num $arg1) : Num

The sqrt method returns the positive square root of the number.

sqrt example #1

  my $number = Data::Object::Number->new(12345);

  $number->sqrt; # 111.108055513541

to

  to(Num $arg1) : ArrayRef

The to method returns an array reference containing integer increasing or decreasing values to and including the limit in ascending or descending order based on the value of the floating-point object.

to example #1

  my $number = Data::Object::Number->new(5);

  $number->to(9); # [5,6,7,8,9]

to example #2

  my $number = Data::Object::Number->new(5);

  $number->to(1); # [5,4,3,2,1]

upto

  upto(Num $arg1) : Any

The upto method returns an array reference containing integer increasing values up to and including the limit.
