NAME

Data::Convert::MicrochipTechnology::Float - Converts Microchip Technology 32-bit float to a number

SYNOPSIS

use Data::Convert::MicrochipTechnology::Float;
my $object = Data::Convert::MicrochipTechnology::Float->new();
my $float=$obj->convert("\0\0\0\0");
print "Float: $float\n";

DESCRIPTION

The format of the PIC 32-bit float is eeeeeeee smmmmmmm mmmmmmmm mmmmmmmm (4-bytes => 8-bit biased exponent, 1-bit sign, 23-bit significand)

The number has value v: v = s * 2**e * m
s = +1 (positive numbers) when the sign bit is 0
s = -1 (negative numbers) when the sign bit is 1
e = Exp - 127 (the exponent is biased with 127)
m = 1.fraction in binary (the significand is the binary number 1 followed by the radix point followed by the binary bits of the fraction). Therefore, 1 = m < 2.

USAGE

CONSTRUCTOR

new

my $object = Data::Convert::MicrochipTechnology::Float->new();

METHODS

convert

my $float=$obj->convert("\0\0\0\0");
my @list=$obj->convert("\0\0\0\0", "\0\0\0\0");
my $listref=$obj->convert("\0\0\0\0", "\0\0\0\0");
my $float=$obj->convert([0,0,0,0]);
my @list=$obj->convert("\0\0\0\0", [0,0,0,0]);
my $listref=$obj->convert("\0\0\0\0", [0,0,0,0]);

float_from_string

my $float=$obj->float_from_string("\0\0\0\0");

float_from_array

my $float=$obj->float_from_array(0, 0, 0, 0);

BUGS

The math introduces floating point rounding errors.

TODO

Add a bit vector capability to eliminate any rounding errors.
