WD JS Number Tools

WD JS Number Tools

When informed factorial or percentage values (Strings), the corresponding mathematical value will be assigned, that is, 10% will be transformed to 0.1 and 3! will be transformed to 6.

The initial value cannot be modified by methods or attributes.

To find the description of the tools presented in this section, it is recommended that you read the following topics:

• Static: lang
• Tools: Number
• Types

abs

wd(number).abs

let a = wd(2048.58);
a.abs; /* returns 2048.58 */
let b = wd("-10%");
b.abs; /* returns 0.1 */

byte

wd(number).byte

let a = wd(2048.58);
a.byte; /* returns "2.00kB" */

dec

wd(number).dec

let a = wd(2048.58);
a.dec; /* returns 0.58 */

fixed

wd(number).fixed(ldec, lint)

Argument	Type	Mandatory	Description
ldec	Integer	No	Number of decimal places to display. (default value 0)
lint	Integer	No	The minimum number of integer characters. (default value 0)

let p = wd(3.456);
p.fixed();    /* returns "3" */
p.fixed(2);   /* returns "3.46" */
p.fixed(2,2); /* returns "03.46" */
p.fixed(5,3); /* returns "003.45600" */

frac

wd(number).frac

let a = wd(2048.58);
a.frac; /* returns "2048 29/50" */

int

wd(number).int

let a = wd(2048.58);
a.int;   /* returns 2048 */

locale

wd(number).locale(currency)

Argument	Type	Mandatory	Description
currency	String	No	Defines the currency code (ISO 4217).

If a suitable value for the "currency" argument is given, it will return a monetary value.

let p = wd(1050.456);
/* if wd.lang == "pt-BR": */
p.locale();      /* returns "1.050,456" */
p.locale("BRL"); /* returns "R$ 1.050,46" */
p.locale("USD"); /* returns "US$ 1.050,46" */
/* if wd.lang == "en-US": */
p.locale();      /* returns "1,050.456" */
p.locale("BRL"); /* returns "R$1,050.46" */
p.locale("USD"); /* returns "$1,050.46" */

ntype

wd(number).ntype

Possible values for ntype are (strings):

Value	Example
zero	0
+infinity	Infinity
-infinity	-Infinity
+integer	3
-integer	-3
+float	0.3
-float	-0.3

let a = wd(2048.58);
a.ntype; /* returns "+real" */

pow10

wd(number).pow10(width)

Argument	Type	Mandatory	Description
width	Number	No	Number of decimal places to display.

let p = wd(3.456);
p.pow10();  /* returns "3.456 x 10⁺⁰" */
p.pow10(2); /* returns "3.46 x 10⁺⁰" */

round

wd(number).round(width);

Argument	Type	Mandatory	Description
width	Number	No	Number of decimal places to round (default value 0).

let p = wd(3.456);
p.round();  /* returns 3 */
p.round(2); /* returns 3.46 */

str

wd(number).str

let a = wd(2048.58);
a.str; /* returns "2.0e+3" */
let b = wd("-10%");
b.str; /* returns "-0.10" */

test

See test method.
