Determine whether two values are roughly equal.

## NAME

near - Determine whether two values are roughly equal.

## SYNOPSIS

**loadrt near \[count=*N*\|names=*name1*\[,*name2...*\]\]**

## FUNCTIONS

- **near.***N* (requires a floating-point thread)

  ## PINS

- **near.*N*.in1 float in**

  - **near.*N*.in2 float in**

  - **near.*N*.out bit out**

  **out** is true if **in1** and **in2** are within a factor of **scale** (i.e., for in1 positive, in1/scale \<= in2 \<= in1\*scale), OR if their absolute difference is no greater than **difference** (i.e., \|in1-in2\| \<= difference).  **out** is false otherwise.

## PARAMETERS

- **near.*N*.scale float rw (default: *1*)**

  - **near.*N*.difference float rw (default: *0*)**
