# NAME

Convert::Number::Greek - Convert between Arabic and Greek numerals

Version 0.02

# SYNOPSIS

```  use Convert::Number::Greek qw'num2greek greek2num';

\$greek_number = num2greek 1996;
# \$greek_number now contains
# "\x{375}\x{3b1}\x{3e1}\x{3df}\x{3db}\x{374}"

\$number = greek2num "\x{3b5}\x{3c3}\x{3c4}\x{3b6}'";
# \$number now contains 567```

# DESCRIPTION

This module provides subroutines for converting between Arabic and Greek numbers.

# FUNCTIONS

num2greek ( NUMBER, { OPTIONS } )

num2greek converts an Arabic numeral to a Greek numeral in the form of a Unicode string the syntax is as follows:

NUMBER is the number to convert. It should be a string of digits, nothing more (see BUGS, below). OPTIONS (optional) is a reference to a hash of boolean options. The options available are as follows:

``` Option Name    Default Value   Description
upper          0               Use uppercase Greek letters
uc             0                "      "       "      "
stigma         1               Use the stigma for 6 as opposed to
sigma followed by tau
arch_koppa     0               Use the archaic koppa instead of
the modern one
numbersign     1               Append a Greek number sign (U+0374)
to the resulting string```

When you specify options, `undef` is treated as false, so

`    num2greek \$some_number, { uc => 1, stigma }`

actually means

`    num2greek \$some_number, { uc => 1, stigma => 0 }`
greek2num ( STRING )

The `greek2num` function parses a Greek numbers and returns the Arabic equivalent.

STRING is a string consisting of a Greek number. Anything following the number will be ignored, but will raise a warning if `use warnings 'numeric'` is on (unless it's just whitespace).

Currently no options are available.

# EXPORTS

None by default, but you get `num2greek` and `greek2num` if you ask for them (politely).

# DIAGNOSTICS

The greek2num function will trigger a "non-numeric" warning if you `use warnings 'numeric'`.

# COMPATIBILITY

This module requires perl 5.8.0 or later, though the earliest version I have tested it with is 5.8.1.

# BUGS

The `num2greek` function does not yet have any error-checking mechanism in place. The input should be a string of Arabic digits, or at least a value that stringifies to such. Using an argument that does not fit this description may produce nonsensical results.
