3. Functional calculation

3.1 Trigonometric functions, inverse trigonometric functions

You can set angle unit, DEG (Degree), RAD (Radian) and GRAD (Grads), using [DEG] key before trigonometric caluclaion.

Example: Angle unit [Radian]
[ALT][DRG] RAD
=0.5

Example: Angle unit [Degree]
[ALT][DRG] DEG
=0.5

Inverse trigonometric functions can be calculated useing [ALT] key
Example: Angle unit [Degree]
[ALT][sin-1] 0.5
=30

3.2 Degree, Minute, Second and time calculation

You can enter Degree, Minute, Second format value and time format value, and convert into real value using [°’”] or [H:M:S] key after calculation.
If you tap [ALT][°’”] or [ALT][H:M:S], the label of [°’”],[H:M:S] switchs each other.

Example:
Convert real value into DMS format 30.5
=30.5
Tap [°’”] key
=30°30’00”
Tap [°’”] key again
=30.5
Time calculation ■1hour 30min + 2hour 45min
Tap [ALT][°’”], then you can find [H:M:S] label.

1[H:M:S]30+2[H:M:S]45
=4:15:00

■Total manufacturing time for 150 parts of 50 sec/item.

0[H:M:S]0[H:M:S]50×150
=2:05:00

(term of settings)
D°M’S”/H:M:S result format → Format

3.3 Calculation of percent

The Panecal can calculate of percent.

(term of settings)
Percent calculation → 100+20% = 120

Example
"20% increase of $50?"
=60

"20% decrease of $50?"
=40

"20% of $50?"
>=10

"what percentage of $50 is $10?"
=20

3.4 Other Functions

Arithmetic, trigonometric, inverse trigonometric, exponential, logarithmic function, power, power root function, factorial, absolute, permutation(nPr) and combination(nCr) functions.

4. Base-N calculation

4.1 Base-N calculation mode

You can swich Base-N mode when there are no characters on the display. Then if you want to swich to HEX mode, tap [CLR] key and [HEX] key.

BIN Switch to BIN mode: [CLR][ALT][BIN]
max. 32 figures (Depends on number of bits setting)
OCT Switch to OCT mode:[CLR][ALT][OCT]
max. 12 figures (Depends on number of bits setting)
DEC Switch to OCT mode:[CLR][ALT][DEC]
Depends on FSE, DIGS
HEX Switch to HEX mode:[CLR][ALT][HEX]
max. 8 figures (Depends on number of bits setting)

4.2 Number base convertion

You can convert Base-N number into other Base-N one.

Example:
(1111)2→(0F)16 [CLR][ALT][BIN]1111[ALT][HEX]
=000F
get octal value from last answer [ALT][OCT]
=0000 0017
get decimal value from last answer [ALT][DEC]
=15


Example: Convert to binary coded decimal(BCD)
(1234)16
(0001 0010 0011 0100)2
[CLR][ALT][HEX]1234[ALT][BIN]
=0001 0010 0011 0100
Binary decimal number (BCD) 0001 0010 0011 0100 can be displayed by inputting decimal 1234 in hexadecimal mode and converting it to binary.

4.3 Logical operations

Logical operations can be performed by tapping [AND], [OR], [XOR], [NOT] on BIN, OCT and HEX mode.

5. Memories

The Value can be registered in memory and used in formulas. There are two types of memory available: M memory and variable memory(A to F).

5.1 Register to M memory

Press and hold the memory key to register the value of the formula with the cursor in the memory.
Example: M memory registration
10+20[M(Long press)]
30→M
30[M+(Long press)]
30→M+
40[M-(Long press)]
40→M-

5.2 Calling M memory

There are two types of M memory calls: value calls and variable calls. Tap [MR (Long press)] to call a value, and tap [ALT] [M] to call a variable.
Memory feature labels that should be in yellow are omitted.

Example: M memory value call
[MR(Long press)]
20
Example] After calling the M memory variable, multiply by 2.
[ALT][M]×2[=]
=40

Example: Calculation using [MC], [M], [M+], [M-]
+(12×2)
+(13×2)
-(14×2)
=22
入力:[MC(Long press)]12×2[M+(Long press)]13×2[M+(Long press)]14×2[M-(Long press)][ALT][M]=

5.3 Using variable memories A to F

Variable memories A to F are available. The variable memory E,F are stored the calculation results of Mod, Pol and Rec.

Example: Calculation using variable memory
A=2
B=3
A×B÷(A+B)
=1.2
入力:2[A(Long press)]3[B(Long press)][ALT][A]×[ALT][B]÷([ALT][A]+[ALT][B])=

Example: Confirm the remainder R of the calculation result of modulo Mod in memory F
123[Mod]45[=]
Q=2
R=33
[ALT][F][=]
=33

It is possible to use the [SHIFT] key instead of long press. In this case, press the target memory key after pressing the SHIFT key.
