Computes the base 2 logarithm of x.

If x is 0, log2(x) is negative infinity. If x is not complex and is less than 0, log2(x) is NaN. The connector pane displays the default data types for this polymorphic function.

Inputs/Outputs

  • cdbl.png x —

    x can be a scalar number, array or cluster of numbers, array of clusters of numbers, and so on.

  • idbl.png log2(x) —

    log2(x) is of the same numeric representation as x. When x is of the form x = a + bi, that is, when x is complex, the following equation defines log2(x):
