NAME ^

File::Rsync::Mirror::Recentfile::FakeBigFloat - pseudo bigfloat support

SYNOPSIS ^

  use File::Rsync::Mirror::Recentfile::FakeBigFloat qw(:all);

ONLY INTERNAL FUNCTIONS ^

These functions are not part of a public interface and can be changed and go away any time without prior notice.

DESCRIPTION ^

We treat strings that look like floating point numbers. If the native floating point support is good enough we use it. If it isn't we make sure no two unequal numbers are treated the same and vice versa. Only comparison operators are supported, no other math.

EXPORT ^

All functions are exported in the :all tag.

_bigfloatcmp ( $l, $r )

Cmp function for floating point numbers that have a larger significand than can be handled by native perl floats.

_bigfloatge ( $l, $r )

Same for ge

_bigfloatgt ( $l, $r )

Same for gt

_bigfloatle ( $l, $r )

Same for lt

_bigfloatlt ( $l, $r )

Same for lt

_bigfloatmax ( $l, $r )

Same for max (of two arguments)

_bigfloatmin ( $l, $r )

Same for min (of two arguments)

$big = _increase_a_bit ( $l, $r )

$big = _increase_a_bit ( $n )

The first form calculates a string that is between the two numbers, closer to $l to prevent rounding effects towards $r. The second form calculates the second number itself based on nextup() in Data::Float.
