Calculadora Simple

Simple calculator with some logarithmic and trigonometric functions.

POWERS AND FACTORIALS
ROOTS
PERCENTAGES
• 100% = 1
• 100 x 20% = 20
• 100 / 20% = 500
• 150 + 30 (20%) = 180
• 150 – 30 (20%) = 120
• When we add or subtract a percentage, the screen displays the amount added or subtracted and the applied percentage in parentheses and dimmed.
FUNCTIONS
• Trigonometric and logarithmic functions → Button + number.
CONST BUTTON
• This button creates a constant operation. For example: Multiplying 5 by a series of numbers: Number + operator + Button. In the example, it would be 5 + 'x' + Button, and from then on, Number + '='. To exit constant mode, press an operator after the number, the 'Clear All' button, or the 'Const' button itself.
DEGREES/RADIANS
• By pressing the selector, you can switch between degrees and radians.
