BigDecimal

Represents arbitrary-precision signed decimal numbers. The representation consists of both a "value" and a "scale". Standard equality (== and the Eq trait) consider both value and scale, numerical equality (are the values the same after the scales have been normalized) is provided by the function numericEquals.

Definitions

def abs(x: BigDecimal): BigDecimal§ Source

Returns the absolute value of x.

def ceil(x: BigDecimal): BigDecimal§ Source

Returns x rounded up to a BigDecimal representing the nearest larger integer value.

def compare(x: BigDecimal, y: BigDecimal): Int32§ Source

Returns 1 if x > y, -1 if x < y, and 0 if x = y.

def dist(x: BigDecimal, y: BigDecimal): BigDecimal§ Source

Returns the distance between x and y.

def floor(x: BigDecimal): BigDecimal§ Source

Returns x rounded down to a BigDecimal representing the nearest smaller integer value.

def fromString(s: String): Option[BigDecimal]§ Source

Parse the string s as an BigDecimal, leading or trailing whitespace is trimmed. A successful parse is wrapped with Some(x), a parse failure is indicated by None.

def max(x: BigDecimal, y: BigDecimal): BigDecimal§ Source

Returns the larger of x and y.

def min(x: BigDecimal, y: BigDecimal): BigDecimal§ Source

Returns the smaller of x and y.

def numericEquals(x: BigDecimal, y: BigDecimal): Bool§ Source

Compare x and y for equality normalizing any difference in scale.

def pow(base: { base = BigDecimal }, n: Int32): BigDecimal§ Source

Returns base raised to the power of n.

def precision(x: BigDecimal): Int32§ Source

Returns the precision of x.

def round(x: BigDecimal): BigDecimal§ Source

Returns x rounded to a BigDecimal representing the nearest integer value.

The rounding may be upwards or downwards. If the rounding up and rounding down are equally close, x will be rounded to an even value (i.e. round(0.5ff64) == 0.0ff64).

def scale(x: BigDecimal): Int32§ Source

Returns the scale of x.

def signum(x: BigDecimal): Int32§ Source

Returns 1 if x > 0, -1 if x < 0, and 0 if x = 0.

def toBigInt(x: BigDecimal): BigInt§ Source

Convert x to a BigInt.

def toPlainString(x: BigDecimal): String§ Source

Returns x as a "plain string" without an exponent field.

def tryToFloat32(x: BigDecimal): Option[Float32]§ Source

Convert x to an Option[Float32].

Returns Some(x as Float32) if the numeric value of x is within the range of Float32, loss of precision may occur.

Returns None if the numeric value of x is outside the range of Float32 (i.e. 1.4E-45 to 3.4028235E38).

def tryToFloat64(x: BigDecimal): Option[Float64]§ Source

Convert x to an Option[Float64].

Returns Some(x as Float64) if the numeric value of x is within the range of Float64, loss of precision may occur.

Returns None if the numeric value of x is outside the range of Float64 (i.e 4.9E-324 to 1.7976931348623157E308).

def tryToInt16(x: BigDecimal): Option[Int16]§ Source

Convert x to an Option[Int16].

Returns Some(x as Int16) if the numeric value of x is within the range of Int16, rounding x towards 0`.

Returns None if the numeric value of x is outside the range of Int16 (i.e. -32768 to 32767).

def tryToInt32(x: BigDecimal): Option[Int32]§ Source

Convert x to an Option[Int32].

Returns Some(x as Int32) if the numeric value of x is within the range of Int32, rounding x towards 0`.

Returns None if the numeric value of x is outside the range of Int32 (i.e. -2147483648 to 2147483647).

def tryToInt64(x: BigDecimal): Option[Int64]§ Source

Convert x to an Option[Int64].

Returns Some(x as Int64) if the numeric value of x is within the range of Int64, rounding x towards 0`.

Returns None if the numeric value of x is outside the range of Int64 (i.e. -9223372036854775808 to 9223372036854775807).

def tryToInt8(x: BigDecimal): Option[Int8]§ Source

Convert x to an Option[Int8].

Returns Some(x as Int8) if the numeric value of x is within the range of Int8, rounding x towards 0`.

Returns None if the numeric value of x is outside the range of Int8 (i.e. -128 to 127).
