# sizeinbase {gmp}

Compute size of a bigz in a base

### Description

Return an approximation to the number of character the integer X would have printed in base b. The approximation is never too small.

In case of powers of 2, function gives exact result.

### Usage

sizeinbase(a, b=10)

### Arguments

- a
- big integer, i.e.
`"bigz"`

- b
- base

### Values

integer of the same length as `a`

: the size, i.e. number of digits, of each `a[i]`

.
