AutoNumeric 1.9.41 is a jQuery plugin that automatically formats currency and numbers as you type on form inputs. It supports most International numeric formats and currency signs including those used in Europe, North and South America, Asia and India lakhs.
You only use the M for a numeric literal, when you cast it's just: decimal dtot = (decimal)doubleTotal; Note that a floating point number is not suited to keep an exact value, so if you first add numbers together and then convert to Decimal you may get rounding errors. Thicc Stroke is a fully featured, variable-width stroke plugin. Supports variable decimal places and custom symbols.
This section discusses the characteristics of the DECIMAL
data type (and its synonyms), with particular regard to the following topics:
Maximum number of digits
Storage format
Storage requirements
The nonstandard MySQL extension to the upper range of
DECIMAL
columns
The declaration syntax for a DECIMAL
column is DECIMAL(
. The ranges of values for the arguments are as follows:M
,D
)
M
is the maximum number of digits (the precision). It has a range of 1 to 65.D
is the number of digits to the right of the decimal point (the scale). It has a range of 0 to 30 and must be no larger thanM
.
If D
is omitted, the default is 0. If M
is omitted, the default is 10.
The maximum value of 65 for M
means that calculations on DECIMAL
values are accurate up to 65 digits. This limit of 65 digits of precision also applies to exact-value numeric literals, so the maximum range of such literals differs from before. (There is also a limit on how long the text of DECIMAL
literals can be; see Section 12.22.3, “Expression Handling”.)
Values for DECIMAL
columns are stored using a binary format that packs nine decimal digits into 4 bytes. The storage requirements for the integer and fractional parts of each value are determined separately. Each multiple of nine digits requires 4 bytes, and any remaining digits left over require some fraction of 4 bytes. The storage required for remaining digits is given by the following table.

For example, a DECIMAL(18,9)
column has nine digits on either side of the decimal point, so the integer part and the fractional part each require 4 bytes. A DECIMAL(20,6)
column has fourteen integer digits and six fractional digits. The integer digits require four bytes for nine of the digits and 3 bytes for the remaining five digits. The six fractional digits require 3 bytes.
DECIMAL
columns do not store a leading +
character or -
character or leading 0
digits. If you insert +0003.1
into a DECIMAL(5,1)
column, it is stored as 3.1
. For negative numbers, a literal -
character is not stored.
DECIMAL
columns do not permit values larger than the range implied by the column definition. For example, a DECIMAL(3,0)
column supports a range of -999
to 999
. A DECIMAL(
column permits up to M
,D
)M
- D
digits to the left of the decimal point.
The SQL standard requires that the precision of NUMERIC(
be exactlyM
,D
)M
digits. For DECIMAL(
, the standard requires a precision of at least M
,D
)M
digits but permits more. In MySQL, DECIMAL(
and M
,D
)NUMERIC(
are the same, and both have a precision of exactly M
,D
)M
digits.

For a full explanation of the internal format of DECIMAL
values, see the file strings/decimal.c
in a MySQL source distribution. The format is explained (with an example) in the decimal2bin()
function.
Decimal Placing Names
mixing freely with Decimals.
My freeware Decimal Plugin adds a new number type, Decimal, to
REALbasic 2007 and higher. Decimal can handle big numbers whose size
is only limited by available memory. Decimal can be freely mixed with
REALbasic's numeric types. The Decimal type can exactly represent any
finite decimal. One can think of a Decimal as two numbers (i, e),
where i is an integer of any length, and e is of Integer type and is
the exponent for base ten. That is:
(i, e) = i x 10^e
The underlying multi-precision library used by my plugin is the GNU
MP Bignum Library (GMP). I chose that instead of Victor Shoup's NTL
because GMP is released under the GNU Lesser General Public License
(LGPL). So Decimal Plugin is released under the LGPL also.
Decimal Plugin is compiled as an OS X Universal, Windows, and Linux
plugin.
Freeware.
