jdk.math.MathContext — clojure-interop/java.math 1.0.5

Immutable objects which encapsulate the context settings which describe certain rules for numerical operators, such as those implemented by the BigDecimal class.

The base-independent settings are:

precision: the number of digits to be used for an operation; results are rounded to this precision

roundingMode: a RoundingMode object which specifies the algorithm to be used for rounding.

*-decimal-128 clj

Static Constant.

A MathContext object with a precision setting matching the IEEE 754R Decimal128 format, 34 digits, and a rounding mode of HALF_EVEN, the IEEE 754R default.

type: java.math.MathContext

*-decimal-32 clj

Static Constant.

A MathContext object with a precision setting matching the IEEE 754R Decimal32 format, 7 digits, and a rounding mode of HALF_EVEN, the IEEE 754R default.

type: java.math.MathContext

*-decimal-64 clj

Static Constant.

A MathContext object with a precision setting matching the IEEE 754R Decimal64 format, 16 digits, and a rounding mode of HALF_EVEN, the IEEE 754R default.

type: java.math.MathContext

*-unlimited clj

Static Constant.

A MathContext object whose settings have the values required for unlimited precision arithmetic. The values of the settings are:

precision=0 roundingMode=HALF_UP

type: java.math.MathContext

->math-context clj

(->math-context set-precision)

(->math-context set-precision set-rounding-mode)

Constructor.

Constructs a new MathContext with a specified precision and rounding mode.

set-precision - The non-negative int precision setting. - int set-rounding-mode - The rounding mode to use. - java.math.RoundingMode

throws: java.lang.IllegalArgumentException - if the setPrecision parameter is less than zero.

equals clj

(equals this x)

Compares this MathContext with the specified Object for equality.

x - Object to which this MathContext is to be compared. - java.lang.Object

returns: true if and only if the specified Object is a MathContext object which has exactly the same settings as this object - boolean

get-precision clj

(get-precision this)

Returns the precision setting. This value is always non-negative.

returns: an int which is the value of the precision setting - int

get-rounding-mode clj

(get-rounding-mode this)

Returns the roundingMode setting. This will be one of RoundingMode.CEILING, RoundingMode.DOWN, RoundingMode.FLOOR, RoundingMode.HALF_DOWN, RoundingMode.HALF_EVEN, RoundingMode.HALF_UP, RoundingMode.UNNECESSARY, or RoundingMode.UP.

returns: a RoundingMode object which is the value of the roundingMode setting - java.math.RoundingMode

hash-code clj

(hash-code this)

Returns the hash code for this MathContext.

returns: hash code for this MathContext - int

to-string clj

(to-string this)

Returns the string representation of this MathContext. The String returned represents the settings of the MathContext object as two space-delimited words (separated by a single space character, '\u0020', and with no leading or trailing white space), as follows:

The string "precision=", immediately followed by the value of the precision setting as a numeric string as if generated by the Integer.toString method.

The string "roundingMode=", immediately followed by the value of the roundingMode setting as a word. This word will be the same as the name of the corresponding public constant in the RoundingMode enum.

For example:

precision=9 roundingMode=HALF_UP

Additional words may be appended to the result of toString in the future if more properties are added to this class.

returns: a String representing the context settings - java.lang.String
