ldexp(x, n)

Compute $x \times 2^n$.


julia> ldexp(2.5, 3)

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.
