FLOATING POINT Directive

FLOATING POINT

Description

Use the FLOATING POINT directive to have ProvideX start using scientific notation

with all numeric data. In scientific notation, a number is represented as a fraction

times ten to some power (e.g., .nnnnn*10^xx is displayed as .nnnnnExx).

In FLOATING POINT mode, no rounding is done on numeric calculations. If the

numeric output is unformatted, ProvideX uses scientific notation (e.g., .314159E+01).

Use the PRECISION directive to end FLOATING POINT mode.
