Propモードの使用例

[highlight_dark]料理の分量を計算する[/highlight_dark]

4人分(200g)のレシピで3人分料理を作る!

4 → 200 → 3 を入力

3人分の分量は150gになります。


[highlight_dark]買い物での値段比較[/highlight_dark]

150g:560円、180g:720円 の牛肉どちらがオトク?

150 → 560 → 180 を入力

150gの牛肉は180gでは672円になるので180g:720円は少々高めのお肉ですね。

 

[highlight_dark]写真のサイズ変更[/highlight_dark]

H480px・W640pxの写真をブログに載せるためW500pxにリサイズ!

640 → 480 → 500 を入力

H375px ですね。

IPractiCalc v2.0 is an innovative calculator with two calculation modes.
These two calculation modes can be used for both everyday shopping and work.


Prop mode can be used to compare prices for shopping or to measure the portion of ingredients for cooking.

Normal mode can be extended to enable you to see the entire calculation formula on-screen and to add or delete values (eg. 100, 200 etc) and codes (eg: +, -, x, /) as you like.
Supported tax inclusive value.

Example cases of Prop mode

[Cooking]
Calculate portion of ingredients

Your recipe book indicates that you need 200g of flour to cook for four. However you only want to cook for three!

How much flour is needed?

Now is the time to use iPractiCalc! First, enter 4 and 200 as fixed values, then enter 3 and tap Calc. The result is 150. You need 150g of flour for three.

[Shopping]
Compare prices during shopping

You are going to buy beef and there are two kinds of beef. One is 500g for $ 4.50 and another one is 600g for $ 5.98.

Which one is cheaper?

Enter 500 and 4.5 as fixed values. Then enter 600 for comparison and tap Calc. The result is $ 5.40. 500g beef will be $ 5.40 if you buy 600g, Therefore 600g for $5.98 beef is slightly more expensive.

[Creating]
Changing photo pixel size

You are trying to upload a photo on your blog. The photographユs height is 480 pixels and the width is 640 pixels. However you need to downsize the photo to fit 500 pixels (both height and width) and no more for the blog.

How many pixels can the height be?

First, enter 640 and 480 as fixed values, then enter 500 for comparison and tap Calc key. The result is that the height is 375 pixels.

Normal Mode Guide

This mode will function as a common calculator (standard algebraic calculator) but the total formula will remain visible in the formula field. You may add, change or delete both values and/ or codes as you wish throughout the calculation.
Please note that this calculator is not a scientific calculator and results are given as you enter values. The Normal mode will calculate 1+2×3=9 as it will not prioritize multiplication and division but simply process from left to right or as you enter values.

Step 5 : Show tax inclusive value

Should you wish to see the tax inclusive value (eg. Japan is 5% sales tax), simply tap Tax key.

Normal Mode Guide  

Step 6

Should a sub-calculation be required in the process of making a calculation in Prop mode, you may switch from Prop mode to Normal mode and the result of the Normal sub-calculation can be instantly sent back to the Prop mode to complete the calculation.
Result can be sent to specified value fields in Prop mode and the mode will switch to Prop mode.
