DEG→RAD FLOOR FNROOT FRAC HMS→ →HMS 13-14 Examples CEILING(3.2) returns 4 CEILING(-3.2) returns -3 Degrees to radians. Converts value from Degrees angle format to Radians angle format. DEG→RAD(value) Example DEG→RAD(180) returns 3.14159265359, the value of π. Greatest integer less than or equal to value. FLOOR(value) Example FLOOR(-3.2) returns -4 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. Fractional part. FRAC(value) Example FRAC (23.2) returns .2 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 Decimal to hours-minutes-seconds. Converts a number or expression in x.x format (number of hours or degrees Using mathematical functions
