Returns
dd +( mm /60)+( ss.ss /3600).
This base-60 entry format lets you:
• Enter an angle in degrees/minutes/seconds
without regard to the current angle mode.
• Enter time as hours/minutes/seconds.

Enters a prime symbol in a differential equation.
A single prime symbol denotes a 1st-order
differential equation, two prime symbols denote a
2nd-order, etc.

expression _ unit
Designates the units for an expression . All unit
names must begin with an underscore.
You can use pre-defined units or create your
own units. For a list of pre-defined units, refer
to the module about constants and
measurement units. You can press:
¥À to select units from a menu, or you
can type the unit names directly.
