What's this?

Supported languages (1)

show languages
Scientific and base calculator that supports the most common functions as well as base conversation and calculation of hexadecimal, binary and decimal values.
CalculatorX supports order of operations which means that 1+2*3 is calculated correctly as 7 and not as 9, while 2^3^4 results 2.41...E+24 and not 4096 (which is calculated incorrectly by many calculators btw.)
In order to calculate any function like sin, cos, asin, etc, you can either press the function key first, followed by the value (or expression), or you can first enter the value (or expression) and then enter the function key. For instance, you can calculate sin(30) by entering 'sin' + '30' or by entering '30' + 'sin'.

Update 1.3:
pressing a key now optionally plays a sound.

    It's good, except when in a phone call and try to use this app, the bottom row of buttons gets cut off. It would be great except for that.
