Converts a Number
into a String
with a given number of digits.
nf()
converts numbers such as 123.45
into strings formatted with a set number of digits, as in '123.4500'
.
The first parameter, num
, is the number to convert to a string. For example, calling nf(123.45)
returns the string '123.45'
. If an array of numbers is passed, as in nf([123.45, 67.89])
, an array of formatted strings will be returned.
The second parameter, left
, is optional. If a number is passed, as in nf(123.45, 4)
, it sets the minimum number of digits to include to the left of the decimal place. If left
is larger than the number of digits in num
, then unused digits will be set to 0. For example, calling nf(123.45, 4)
returns the string '0123.45'
.
The third parameter, right
, is also optional. If a number is passed, as in nf(123.45, 4, 1)
, it sets the minimum number of digits to include to the right of the decimal place. If right
is smaller than the number of decimal places in num
, then num
will be rounded to the given number of decimal places. For example, calling nf(123.45, 4, 1)
returns the string '0123.5'
. If right is larger than the number of decimal places in num
, then unused decimal places will be set to 0. For example, calling nf(123.45, 4, 3)
returns the string '0123.450'
.
