This also works for while loops.
Ruby method floor.
Floor ndigits integer or float click to toggle source returns the largest number less than or equal to int with a precision of ndigits decimal digits default.
How to extract a substring a substring is a smaller part of a string it s useful if you only want that specific part like the beginning middle or end.
If it wasn t clear yet ruby is very flexible here s yet another method for creating a loop.
Ruby program that uses floor ceil number 1 1 puts number use floor to remove the fractional part.
This will produce the following result.
Floor ndigits integer or float click to toggle source returns the largest number less than or equal to float with a precision of ndigits decimal digits default.
As you may have guessed there is a difference between procs and lambdas see below so you need to be aware of whether you re using ruby 1 8 or 1 9.
It is basically equivalent to proc new in ruby 1 9 but not in ruby 1 8.
They can be called without a receiver functional.
When the precision is negative the returned value is an integer with at least ndigits abs trailing zeros.
For ve precision.
For ve precision.
When you use break you ll end the loop immediately so keep that in mind.
The methods go lower and higher to the next integer.
Returns self when ndigits is zero or positive.
The key here is the ruby break keyword.
Ruby float floor method with example.
1 upto 5 i puts i which prints numbers from 1 to 5.
Usr bin ruby num 12 40 puts num floor 12 puts num 10 22 40 puts num integer.
Floor puts result1 use ceil to move to the next highest integer.
If you re using 1 9 there is a way to find out if you re dealing.
False as num is a float.
In ruby 1 8 the proc method is equivalent to lambda.
Smallest number to float with a ndigits decimal point precision.
Ceil puts result2 output 1 1 1 2.
Ruby built in functions since the kernel module is included by object class its methods are available everywhere in the ruby program.
When the precision is negative the returned value is an integer with at least ndigits abs trailing zeros.
