HH\Lib\Math\base_convert

Converts the given string in base $from_base to base $to_base, assuming letters a-z are used for digits for bases greater than 10

namespace HH\Lib\Math;

function base_convert(
  string $value,
  int $from_base,
  int $to_base,
): string;

The conversion is done to arbitrary precision.

• To convert a string in some base to an int, see Math\from_base().
• To convert an int to a string in some base, see Math\to_base().

Parameters

• string $value
• int $from_base
• int $to_base

Returns

• string

Examples

$result1 = Math\base_convert("30", 10, 16);
echo "30 in base 10 is $result1 in base 16 \n";

$result2 = Math\base_convert("2f", 16, 10);
echo "2f in base 16 is $result2 in base 10 \n";

$result3 = Math\base_convert("1111", 2, 16);
echo "1111 in base 2 is $result3 in base 16 \n";
