Definitions (136)

decimal.bend

• def Decimal.class.sym
• def Decimal.class.if
• def Decimal.class
• type ScanWhere the reader is.
• def Decimal.read.lead
• def Decimal.read.push
• def Decimal.read.expponytail: exponents past 100000 in magnitude are refused, since 1e100000 materializes 100000 digits; raise the bound if a caller needs more.
• def Decimal.read.step
• def Decimal.read.go
• def Decimal.read.abs
• def Decimal.read.coefThe coefficient; ds holds only digits, so read cannot fail.
• def Decimal.read.digits
• def Decimal.read.shiftA negative exponent adds scale; a positive one spends scale, then multiplies.
• def Decimal.read.fin
• def Decimal.read[+-]digits[.digits][(e|E)[+-]digits], a superset of JSON's number grammar (it also takes a leading + and leading zeros).

rational.bend

• type Rationalnum / den with den > 0 and gcd(num, den) = 1, so zero is 0/1 and equal values are equal terms.
• def Rational.low
• def Rational.normn / d for a nonzero d.
• def Rational.from_bigint
• def Rational.make.if
• def Rational.maken / d in lowest terms, or None when d is zero.
• def Rational.from_decimal
• def Rational.to_decimalThe exact decimal, or None when it repeats (den has a factor besides 2, 5).
• def Rational.neg
• def Rational.is_zero
• def Rational.add
• def Rational.sub
• def Rational.mul
• def Rational.diva / b, or None when b is zero.
• def Rational.cmpDenominators are positive, so cross-multiplying keeps the order.
• def Rational.show.if
• def Rational.show"n/d", or "n" when the denominator is 1.
• def Rational.read.frac
• def Rational.read.dec
• def Rational.read.parts
• def Rational.read"n/d" with BigInt sides (normalized; a zero d is None), or any number Decimal.read takes, such as "-1.25" or "3e-2".
