Where's the Error? - toml_12953 - 08-30-2021 03:04 PM
I'm trying to run the following program on my Prime (both emulator and physical) and it gives me a syntax error in line 9. I've been looking at it and looking at it and I can't see the error. What am I doing wrong?
Code:
#PYTHON name
from math import *
t=eval("ticks()")
loops=1000
for i in range(0,loops):
r0=10
while True:
x=r0
x+=1
x-=4.567ᴇ−4
x+=70
x-=69
x*=7
x/=11
r0-=1
if r0<=0:
break
x=log(x)
x=sin(x)
x=sqrt(x)
x=sqrt(x)
print(x)
t=(eval("ticks()")-t)/1000
print("Index:",34/t*loops)
#end
EXPORT calcperf()
BEGIN
PYTHON(name);

With a few changes your program runs and returns:
0.880981899968678
Index: 1172413.79310345
The changes I made:
- add 'from hpprime import *' at the beginning
- replace the 'ᴇ−' on line 9 by standard 'E-' letters, it seems that the special character codes used by the Prime for E and minus signs are not supported by Python.

Thank you!
Now that you've solved it. I have to say of course! I should have known the ticks function is found in the hpprime module but the exponent error is more subtle. It makes sense, though.
