Imzap {complexplus} | R Documentation |

## Rounding of Null Imaginary Part of a Complex Number

### Description

imaginary parts with values very close to 0 are 'zapped', i.e. treated as 0. Therefore, the number becomes real and changes its class from complex to numeric.

### Usage

```
Imzap(x, tol = 1e-06)
```

### Arguments

`x` |
a scalar or vector, real or complex. |

`tol` |
a tolerance, |

### Examples

```
x1 <- 1:100
x2 <- c(1:98,2+3i,0-5i)
x3 <- c(1:98,2+0i,7-0i)
x4 <- complex(real = rnorm(100), imaginary = rnorm(100))
Imzap(x1) # inocuous with real vectors
Imzap(x2) # 1 single element is enough to turn the vector into complex
Imzap(x3) # removes extra 0i and changes class from from complex to numeric
Imzap(x4) # inocuous with complex vectors with non-null complex part
```
