Rosacea is a chronic condition characterized by redness and inflammation of the skin around the nose, cheeks and forehead. The exact cause of rosacea is unknown and the triggers can vary from case to case. According to Rosacea.org, the most common triggers include sun exposure, emotional stress and heat.
A fraction (from Latin fractus, broken) represents a part of a whole or, more generally, any number of equal parts. When spoken in everyday English, a fraction describes how many parts of a certain size there are, for example, one-half, eight-fifths, three-quarters.
Also, most fractional measurements in science are reported as decimal fractions, as opposed to fractions with any other system of denominators. A decimal data type could be implemented as either a floating-point number or as a fixed-point number. In the fixed-point case, the denominator would be set to a fixed power of ten. In the floating-point case, a variable exponent would represent the power of ten to which the mantissa of the number is multiplied.
