round: rounding of numers

In GPUmatrix: Basic Linear Algebra with GPU

rounding of numers

Description

It mimics the base function 'round' to operate on gpu.matrix-class objects. This function rounds the values in its first argument to the specified number of decimal places (default 0).

Usage

## S4 method for signature 'gpu.matrix.tensorflow,ANY'
round(x)
## S4 method for signature 'gpu.matrix.torch,missing'
round(x,digits)
## S4 method for signature 'gpu.matrix.torch,numeric'
round(x,digits)
## S4 method for signature 'gpu.matrix.tensorflow,missing'
round(x,digits)
## S4 method for signature 'gpu.matrix.tensorflow,numeric'
round(x,digits)

Arguments

x	a gpu.matrix.
digits	integer indicating the number of decimal places (round) or significant digits (signif) to be used.

Details

The function round internally calls the corresponding function of the library torch or tensorflow (depending on the type of input gpu.matrix-class).

The behaveour of the function mimics the 'base' function round. Note that for rounding off a 5, the function will consider "go to the even digit". Therefore, round(2.5) = 2 and round(3.5) = 4. For more details see round, and torch_round.

If the input gpu.matrix-class object is stored on the GPU, then the operations will be performed on the GPU. See gpu.matrix.

Value

The function will return a gpu.matrix-class object with the rounded values.

round, and torch_round.

Examples

## Not run: 

a <- gpu.matrix(rnorm(9),3,3)
round(a,digits = 3) #round to the third digit



## End(Not run)
