Description

Numbers in Jaf are 64-bit floating point values. They can be integers or decimals.

Syntax

42          # integer
3.14        # floating point
-10         # negative
1e6         # scientific notation (1,000,000)
2.5e-3      # scientific notation (0.0025)

Examples

Basic numbers

x = 42
y = 3.14
z = -10
print(x)
print(y)
print(z)
# Output:
# 42
# 3.14
# -10

Scientific notation

big = 1e6
small = 2.5e-3
print(big)
print(small)
# Output:
# 1000000
# 0.0025

Arithmetic

a = 10
b = 3.5
print(a + b)   # 13.5
print(a - b)   # 6.5
print(a * b)   # 35
print(a / b)   # 2.857142857142857

Comparison

print(5 > 3)     # 1 (true)
print(5 == 5)    # 1 (true)
print(3.14 < 2)  # 0 (false)

Notes

• All numbers are stored as double-precision floats
• Integers and decimals can be mixed in operations
• Division always returns a float
