## Module overview

The `lang.decimal` module corresponds to the `decimal` basic type.


Returns the IEEE absolute value of a decimal value.



decimal

Rounds a decimal up to the closest integral value.



ceiling

smallest (closest to -∞) decimal value not less than parameter `x` that is a mathematical integer


Rounds a decimal down to the closest integral value.



floor

largest (closest to +∞) decimal value not greater than parameter `x` that is a mathematical integer.


Returns the decimal value represented by a string.

`s` must follow the syntax of DecimalFloatingPointNumber as defined by the Ballerina specification
with the following modifications
- the DecimalFloatingPointLiteral may have a leading `+` or `-` sign
- a FloatingPointTypeSuffix is not allowed
This is the inverse of function ``value:toString`` applied to an `decimal`.



fromString

string

decimal representation of the argument or error


error

Returns the maximum of one or more decimal values.



maximum value of parameter `x` and all the parameter `xs`


Returns the minimum of one or more decimal values.



minimum value of parameter `x` and all the parameter `xs`.


quantize

decimal value from which to get the quantum


Round a decimal to a specified number of digits.
Returns the decimal value that has an exponent of `-fractionDigits`
and is closest to `x`.
If there are two such values, returns the one whose final digit is even
(this is the round-to-nearest rounding mode, which is the default for IEEE
and for Ballerina).
A value of `fractionDigits` greater than 0 thus corresponds to the number of digits after the decimal
point being `fractionDigits`; a value of 0 for `fractionDigits` rounds to an integer.
Note that IEEE 754 roundToIntegralTiesToEven operation differs from `round` with `fractionDigits` as 0, in that
roundToIntegralTiesToEven will return a value with a positive exponent when the operand has a positive exponent.
Note that `<int>x` is the same as `<int>x.round(0)`.



round

the number of digits after the decimal point


fractionDigits

closest decimal value to `x` that is an integral multiple of 10 raised to the power of `-fractionDigits`


Returns the sum of zero or more decimal values.



sum of all the parameter `xs`; 0 if parameter `xs` is empty
