Qalculate! (vmesnik Qt)

Changes:

• Add temporary check box to function edit dialog
• Insert decimal separator (regardless of reported key symbol) when separator key is pressed on keyboard number pad
• Customizable number bases font
• Use slightly larger font size and wider letter spacing for binary digits, by default, and add option to use bold font for binary "1"
• Show tooltip with index and decimal value of bit when mouse is over binary digit in number bases view
• Preserve base of current expression when switching input number base using keypad buttons
• New function: ymd() (returns the number of calendar years, months, and days between two dates)
• Return exact value for more argument values in lambertw() function
• Integrate sqrt(ax + b)/x and 1/(x × sqrt(ax² + bx + c))
• Do not use same "n" variable for different unknown integer values in equation result (e.g. e^e^x = 1)
• Solve e^x = ln(x), a × sin(x) = a × tan(x), and a × sin(x) = −a × tan(x)
• Solve f(x) = f(x²) and f(x) = −f(x²) for trigonometric functions, and exponentiation
• Do not return x = −infinity as solution for a^x = 0
• Fix a = 1 and b = 1 solution for a^x = b when the value of a and b are unknown
• Fix uncertainty propagation with duplicate equal data set functions
• Fix division by zero warning for some expressions with zero quantity (e.g. "1 m × 0 kg")
• Fix trigonometric functions with function in argument not calculated when angle unit is not radians
• Fix result containing interval with zero as lower value not displayed automatically
• Fix inconsistent (over)use of secondary exchanges rate sources
• Fix number of decimals for currency quantity when currency is placed before quantity
• Minor bug fixes and feature enhancements
