# PocketCalcSheet Support

2021年1月22日ぽけっと計算表

This page is the support page of the ios application “CalcSheet”. ## Application overview

It is a calculation sheet application that can save calculation formulas. By referring to the saved named variable, it display the calculation result calculated by combining functions as a natural mathematical expression.

## Restrictions on application function

• The maximum number of formulas that can be registered is 8.
• You can include another variable in the variable expression, but it is calculated up to twice with one calculation (completion of numerical value input). When values are hierarchically referenced, updating of values is not completed, so it is necessary to perform a numeric input completion operation until computation is completed. For the same reason, the application will not crash even if use circular reference.
• In order to display natural formulas, it is a condition that variable names do not contain double-byte characters. If you are using a variable name containing double-byte characters, only the formulas you entered are displayed.Natural expression display has limitations. For example, 2^2^2 will be and will not be displayed as expected.(It becomes the expression of )
• You can not use symbols in variable names.

## Available functions

・sqrt()
ex)sqrt(2)：return ・log()
ex)log(2)：return ・ln()
ex)ln(2)：return ・exp()
ex)exp(2)：return ・sin()
ex)sin(2)：The unit of the argument is degrees (not radians). Because it is sin2°, it returns 0.034899…

・cos()
例)cos(2)：The unit of the argument is degrees (not radians). Because cos2°, it returns 0.999390…

・tan()
例)tan(2)：The unit of the argument is degrees (not radians). Because it is tan2°, it returns 0.034920…

・dtor()
例)dtor(2)：Convert degrees to radians. Convert 2° to 0.0349065…radians.

・rtod()
例)rtod(2)：Convert radians to degrees. Convert 2radians to 114.59155…°

・asin()
例)asin(2)：The unit of the argument is degrees (not radians). Returns ・acos()
例)acos(2)：The unit of the argument is degrees (not radians). Returns ・atan()
例)atan(2)：The unit of the argument is degrees (not radians). Returns ・random(,)
例：random(1,2)：The first argument is the lower limit value of the random number, and the second argument is the upper limit value. Returns a random number between 1 and 2.

・pi()
Return π(3.141592…). It is used as a variable.

・e()
Returns the Napier number e(2.7182818…). It is used as a variable.
