SYNOPSIS

real r
double precision dp
integer i

i = exponent(r1)

i = exponent(dp1)

DESCRIPTION

exponent returns the value of the exponent of its real or double precision argument as a power of 2. 

If the value of the argument is 0.0 then exponent returns 0. 

For any argument x the following is true:
x = fraction(x) ∗ 2 ∗∗ exponent(x)
