SPACING(X)

Purpose

Returns the absolute spacing of the model numbers near the argument value.

Class

Elemental function

Argument type and attributes

X

must be of type real.

Result type and attributes

Same as X.

Result value

If X is not 0, the result is:

2.0^{EXPONENT(X) - DIGITS(X)}

If X is 0, the result is the same as that of TINY(X).

SPACING (3.0) = 2.0^{2 - 24} = 2.0^(-22) See Real data model.
