Eval a real at a given precision : evalf and Digits, DIGITS)

Input :
1+1/2
Output :
3/2
Input :
1.0+1/2
Output :
1.5
Input:
exp(pi*sqrt(20))
Output :
exp(pi*2*sqrt(5))
With evalf, input :
evalf(exp(pi*2*sqrt(5)))
Output :
1263794.75367
Input :
1.1^20
Output :
6.72749994933
Input :
sqrt(2)^21
Output :
sqrt(2)*2^10
Input for a result with 30 digits :
Digits:=30
Input for the numeric value of e$\scriptstyle \pi$$\scriptstyle \sqrt{{163}}$:
evalf(exp(pi*sqrt(163)))
Output :
0.262537412640768743999999999985e18
Note that Digits is now set to 30. If you don't want to change the value of Digits you may input
evalf(exp(pi*sqrt(163)),30)
