# ldexp

ldexp(x, n)

Compute $x \times 2^n$.

## Examples

```
julia> ldexp(2.5, 3)
20.0
```

This example demonstrates the usage of `ldexp`

function to compute `2.5`

times `2^3`

, which results in `20.0`

. The function `ldexp`

calculates the product of the given value `x`

and `2`

raised to the power of `n`

. It is particularly useful for scaling values by powers of two.

Common mistake example:

```
julia> ldexp(3, 2.5)
ERROR: MethodError: no method matching ldexp(::Int64, ::Float64)
```

In this example, the mistake is passing a floating-point value (`2.5`

) as the second argument (`n`

). The `ldexp`

function expects an integer value for the exponent. Be sure to provide the correct types of arguments to avoid such errors.
