Converting IEEE754 64 bit binary to float in 32bit php version: function getDouble($bits) { if( strlen(binary_data)!=64 ) throw new Exception("wrong binary data"); $sign = $digits[0]; $exp = bindec(substr($bits, 1, 11)) - 1023; $mantissa_length = 30; // This is max workable length for 32bit representation of mantissa.
