## Manual

## Getting startedDownloadYou can download the installation package here. InstallationUnzip the package "yc.zip", execute "setup.exe" and follow instructions of the installer. RunningDouble-click the " yoshinoCALC" icon in the program of the start menu.## Conventional ViewConventional View is one of the two aspects of yoshinoCALC. The software emulates a conventional sceintific calculator. I don't think you need a detailed manual to use it. The followings are explanations for some unusual keys.deg
You can change units of angle between arc
This is to calculate arcsine, arccosine and arctangent.
sin hyp
This is to calculate hyperbolic sine, cosine, tangent. The way of using is the same as that of FOn/FOff
By clicking this button, you can turn on and off the mark "fix" at the left-bottom corner of the top text box. While "fix" is on, a small fraction less than 10 [{( and )}]
These are parentheses. You can make a hyerarchy structure like below. 2*((2+3)+(5-1)): "2" + "*" + "[{(" + "[{(" + "2" + "+" + "3" + ")}]" + "[{(" + "5" + "-" + "1" + ")}]" + ")}]" kin and kout
You can store up to six results in the six smaller boxes by using the "kin" key with a number key like "kin" + "1". Press "kout"+"1" and so on to reuse a stored number. *1.05
Only this key is related not to science but to economy. This key is to calculate a price of something inclding a tax. Although the tax rate is 5% in Japan now, you might want to change the rate in your country. Then right-click on the "1.05" key and select the context menu "change tax rate". A dialog window opens and you can enter a new number in a text box. The same thing can be done by selecting a menu [Help]-[Change Tax Rate]. ## History ViewHistroy View is the other aspect of yoshinoCALC. You can evalute an expression made of following elements. The last result is copied to Clipboard as text. You can recall expressions in the list by "↑" and "↓" keys.NumbersYou can enter an integer, a real number and even one with an index numbers as follows. But all the numbers will be treated as double-precision ones.
1234 ConstantsYou can enter π and e (Napier's number) as well as important natural constants by using following symbols. Units of the natural constants are of SI.
