Class Method Summary

• .convert(x, type, mode = :approx) ⇒ Object

  This is not a module function: this provides a shorthand access to Nio::Fmt.convert.

• .Fmt(options = nil) ⇒ Object
• .gcd(a, b) ⇒ Object
• .nio_convert(x, type, mode = :approx) ⇒ Object

  This module function can be used after import Nio.

• .nio_float_to_bigdecimal(x, prec) ⇒ Object

Class Method Details

.convert(x, type, mode = :approx) ⇒ Object

This is not a module function: this provides a shorthand access to Nio::Fmt.convert

# File 'lib/nio/sugar.rb', line 26

def Nio.convert(x, type, mode=:approx)
  Nio::Fmt.convert x, type, mode
end

.Fmt(options = nil) ⇒ Object

# File 'lib/nio/fmt.rb', line 1283

def Fmt(options=nil)
  Fmt.default(options)
end

.gcd(a, b) ⇒ Object

# File 'lib/nio/repdec.rb', line 500

def gcd(a,b)
  while b!=0 do
    a,b = b, a.modulo(b)
  end
  return a.abs;
end

.nio_convert(x, type, mode = :approx) ⇒ Object

This module function can be used after import Nio

# File 'lib/nio/sugar.rb', line 33

def nio_convert(x, type, mode=:approx)
  Nio::Fmt.convert x, type, mode
end

.nio_float_to_bigdecimal(x, prec) ⇒ Object

:nodoc:

# File 'lib/nio/fmt.rb', line 1287

def nio_float_to_bigdecimal(x,prec) # :nodoc:
  if prec.nil?
    x = Fmt.convert(x,BigDecimal,:approx)
  elsif prec==:exact
    x = Fmt.convert(x,BigDecimal,:exact)
  else
    x = BigDecimal(x.nio_write(Nio::Fmt.new.prec(prec,:sig)))
  end
  x
