NAME

CTK::TFVals - True & False values conversions

VERSION

Version 1.01

SYNOPSIS

use CTK::TFVals;

# Undef conversions
uv2zero( $value ); # Returns 0 if value is undef
uv2null( $value ); # Returns "" if value is undef (null/empty/void)
                   # Aliases:  uv2empty, uv2void

# False conversions
fv2undef( $value ); # Returns undef if value is false
fv2zero( $value ); # Returns 0 if value is false
fv2null( $value ); # Returns "" if value is false (null/empty/void)
                   # Aliases:  fv2empty, fv2void

# True conversions
tv2num( $value ); # Returns 0 unless value ~ ([+-])?\d+
                  # Aliases: tv2number
                  # Check-function: is_num
