# ERFC

Formulas / ERFC
Calculate the complementary ERF function.
`ERFC(X)`
• X - required, lower bound for integrating

## Examples

• `=ERFC(1)`

The ERFC function is used to calculate the complementary error function of a number. This means that it calculates the area under the normal distribution curve to the right of a specified value. For example, this formula calculates the area under the normal distribution curve to the right of 1. The result is 0.157299207050287.

• The ERFC function can also be used to calculate the probability of a value being greater than a certain number. For example, if you want to calculate the probability of a value being greater than 1, you can use the ERFC function with an argument of 1. The result is 0.842700792949713, which is the probability of a value being greater than 1.

The ERFC function can also be used to calculate the probability of a value being less than a certain number. For example, if you want to calculate the probability of a value being less than 1, you can use the ERFC function with an argument of -1. The result is 0.842700792949713, which is the probability of a value being less than 1.

The ERFC function can also be used to calculate the probability of a value being between two numbers. For example, if you want to calculate the probability of a value being between 1 and 2, you can use the ERFC function with an argument of 1 and -2. The result is 0.682689492137086, which is the probability of a value being between 1 and 2.

## Summary

The ERFC function is a single argument function that integrates between x and infinity, returning the complementary ERF function. It requires an X argument as the lower bound.
