KGL
A ruby gem for personal use.
Installation
$ gem install kgl
Usage
Integer#name(lang)
Returns the natural number expression for self in specific natural language. Available languages are the follows.
lang |
Language |
|---|---|
"j" |
Japanese |
"a" |
American English (a billion is 10**9) |
"b" |
British English (a billion is 10**12) |
Math.#ln(anti_logarithm)
An alias of original Math.#log. It returns the natural logarithm of anti_logarithm.
Math.#log(base, anti_logarithm=base.tap{base=Math::E})
Returns the logarithm of anti_logarithm to base base.
Math.#lg(anti_logarithm)
Returns the logarithm of anti_logarithm to base 2.
Float#to_r, String#to_r
Returns Rational value of self.
Float#to_r_exact
Returns exact Rational value of self, that may not be desirable for usual usage.
For instance, (0.1).to_r_exact returns (3602879701896397/36028797018963968) while (0.1).to_r returns (1/10).
Rational#approx_reduction(all=false)
Without the following conditions, this returns Rational approximation of self with smaller denominator, by using Stern-Brocot tree.
If all is true, this returns an Array includes all the path to self of the Stern-Brocot tree.
When self==(0/1) and all is false, this returns self.
When self==(0/1) and all is true, this returns a pair of negative and positive Rational with least denominator which is converted to 0.0 by Rational#to_f. For IEEE 754 compliant environments, the value would be -/+ Rational(1, (((1<<67)-0x4008)<<1008)).
When self.denominator==1 and all is false, this returns a Rational value with least absolute numerator which is converted to self.to_f by Rational#to_f.
When self.denominator==1 and all is true, this returns a pair of Rationals with least and greatest numerator which are converted to self.to_f by Rational#to_f.
When self.numerator.abs==1 and all is false, this returns a Rational value with least denominator which is converted to selft.to_f by Rational#to_f.
When self.numerator.abs==1 and all is true, this returns a pair of Rationals with least and greatest denominator which are converted to self.to_f by Rational#to_f.
Integer#to_msm(fps=59.94)
Returns "[minutes]:[seconds].[milliseconds]" which corresponds to self frames.
The submilliseconds will be rounded. fps is frames per second.
