计算字符串数学公式
支持的运算符和函数:
- 基本运算:+, -, *, /, //, %, **
- 比较运算:>, <, >=, <=, ==, !=
- 数学函数abs, pow, round, ceil, floor, sqrt, exp, log, log10
- 三角函数sin, cos, tan, asin, acos, atan
- 常量pi, e
Args:
formula: 数学公式字符串可以使用变量a、b、c、d
a: 变量a的值
b: 变量b的值
c: 变量c的值
d: 变量d的值
Returns:
计算结果
Examples:
>>> evaluate_formula("a + b", 1, 2)
3.0
>>> evaluate_formula("pow(a, 2)", 5)
25.0
>>> evaluate_formula("ceil(a / b)", 5, 2)
3.0
>>> evaluate_formula("(a>b)*b+(a<=b)*a", 5, 3)
3.0
>>> evaluate_formula("(a>b)*b+(a<=b)*a", 2, 3)
2.0
