FNROOT

Function root-finder (like the Solve aplet). Finds the value

 

for the given variable at which expression most nearly

 

evaluates to zero. Uses guess as initial estimate.

 

FNROOT(expression, variable, guess)

 

Example

 

 

FNROOT(M*9.8/600-1,M,1) returns

 

61.2244897959.

 

FRAC

Fractional part.

 

 

FRAC(value)

 

 

Example

 

 

FRAC (23.2) returns .2

HMS→

Hours-minutes-seconds to decimal. Converts a number or

 

expression in H.MMSSs format (time or angle that can

 

include fractions of a second) to x.x format (number of

 

hours or degrees with a decimal fraction).

 

HMS→(H.MMSSs)

 

 

Example

 

 

HMS→(8.30) returns 8.5

→HMS

Decimal to hours-minutes-seconds. Converts a number or

 

expression in x.x format (number of hours or degrees

 

with a decimal fraction) to H.MMSSs format (time or

 

angle up to fractions of a second).

 

→HMS(x.x)

 

 

Example

 

 

→HMS(8.5) returns

8.3

INT

Integer part.

 

 

INT(value)

 

 

Example

 

 

INT(23.2) returns

23

MANT

Mantissa (significant digits) of value.

 

MANT(value)

 

Example

MANT(21.2E34) returns 2.12
