MAX_DOUBLE_CLEN
Maximum number of characters in a serialized double is
26 (at least for Sun JDK; 19 digits for mantissa, 3 for exponent,
signs for mantissa and exponent, decimal point, 'E'):
but let's pad it up a little bit just to play it safe.

static int |
MAX_FLOAT_CLEN
JDK serializes floats same way as doubles, so let's
reserve as much space
|
static int |
MAX_INT_CLEN
Maximum number of characters in a serialized integer is
11; one for (minus) sign, and then up to 10 digits
|
static int |
MAX_LONG_CLEN
Maximum number of characters in a serialized long is
21; one for (minus) sign, and then up to 20 digits
