# RRSPACING

Elemental Intrinsic Function (Generic): Returns the reciprocal of the relative spacing of model numbers near the argument value.

result = RRSPACING (x)

x | (Input) Must be of type real.

## Results

The result type and kind are the same as x. The result has the value | x* b -e| x b p. Parameters b, e, p are defined in Model for Real Data.

## Example

If -3.0 is a REAL(4) value, RRSPACING (-3.0) has the value 0.75 x 2 24.

The following shows another example:

     REAL(4) res4
     REAL(8) res8, r2
     res4 = RRSPACING(3.0)  ! returns 1.258291E+07
     res4 = RRSPACING(-3.0) ! returns 1.258291E+07
     r2 = 487923.3
     res8 = RRSPACING(r2)   ! returns 8.382458680573952E+015
     END
