M#Math for iPad app for iPhone and iPad

For performace test, Free Version (M#Math Mini) for iPhone can be installed on the iPad ( Search msharp ).

M#Math works 100% offline, and in an expression-look-alike style.

▣ feet and inches (ftin)

53 ; // 5 feet 3 inches in meter
ans = 1.6002

5 3 * 3 0.25 >> yd2 ; // area of plate in [yd²]
ans = 1.76215 [yd²]

▣ coupled nonlinear equations

3β = 2α+1, 4α³β + 5αβ³ = 4

are solved starting from (α,β) = (1,1) by the following command

solve .α.β {1,1} ( 3β = 2α+1, 4α³β + 5αβ³ = 4 );

to reach at one solution

ans =
[ 0.77734 ]₁
[ 0.85156 ]₂

▣ Unit conversion is fast and convenient. For example, 80℉ Fahrenheit is at once converted into
80f >> ;

26.6667 ℃
80 F
539.67 R
299.817 K
ans = 299.817
