The RADIX function returns the number base of the physical representation of a number.

## Syntax

RADIX (x)

*x* is INTENT(IN) and must be of type INTEGER or REAL.

The result is a default INTEGER scalar whose value is the number base of the physical representation of *x*. This value is two for all kinds of INTEGERs and REALs.

## Example

write(*,*) radix(2.3) ! writes 2
