Formatting Numeric Values for Display

The following routines are used to convert RealObj (single floating-point) and CplxObj

(pair of floating-points) values into displayable strings. These routines do not display the

string.

Entry Points

FormReal Converts a RealObj in OP1 into a displayable string and specify the

maximum width allowed for the string. If the current mode setting is SCI

or ENG, the output string will reflect the setting. The value will be

Rounded based on the maximum width entered and the current FIX

setting.

FormBase Converts a RealObj in OP1 into a displayable string. Uses the current

mode settings SCI, ENG, NORMAL, and FIX settings to format the

string. The output can also be formatted as a fraction, or a degrees-

minutes-seconds (DMS) number. If a value cannot be represented in

the desired format, it defaults back to decimal.

FormEReal Converts a RealObj in OP1 into a displayable string and specify the

maximum width allowed for the string. All mode settings are ignored.

FormDCplx Converts a CplxObj value in OP1/OP2 into a displayable string. Uses

the current mode settings SCI, ENG, NORMAL, FIX setting, and

complex output settings a + bi and re^θ

θθ

θi to format the string. The

output can also be formatted as a fraction or a degrees-minutes-

seconds (DMS) number. If a value cannot be represented in the

desired format, it defaults back to decimal.
