Ok so it's probably just easier to use words. No.

The symbol ≈ means approximately the same or about equal. Would taking an Editor-in-chief position at a mid-tier journal be good strategy for a tenure track professor? Rounding means replacing a number with an approximate value that has a shorter, simpler, or more explicit representation. About Us
