It is easily possible to perform an operation with two operands of different datatypes. In this case, the result gets the datatype of the left operand.

Example:

a = 2
b = 1.7
# Result is a float
Print (b+a)
3.7

# Result is an integer, 3.7 rounded to 4
Print (a+b)
4

This simple rule permits a large number of useful applications:

• Output formatting

pi = 3.14159265359
Print (0.00+pi)
3.14

• Convert from floats to integers

pi = 3.14159265359
a = 0+pi
Print (a)
3

And another example to check if a rounded number is odd or even, which considers the fact that the modulo operator '%' can only be applied to integers:

a = 7.6
if (0+a)%2
  print 'a is odd'
else
  print 'a is even'

a is even

• Convert to and from string

a = "2"
b = 5+a
Print (b)
7

a = 2
b = "5"+a
Print (b)
"52"

a = 5
b = "2"*a
Print (b)
"22222"

Remember to be careful when writing more complicated mathematical expressions:

• DEFINE FLOATS WITH AN EXPONENT TO GAIN MAXIMUM PRECISION
• PUT INTEGERS AND LOW PRECISION FLOATS ON THE RIGHT SIDE TO PREVENT THEM FROM CONVERTING OTHER FLOATS

Examples for calculating the average of two numbers:

If b and c are integers and you want to obtain a float result, put the 0.5 on the left side:

a=0.5*(b+c)

If b and c are high precision floats, put the 0.5 on the right side (or use 5e-1) to prevent it from reducing the precision of the result to one decimal:

a=(b+c)*0.5
