float
| fneg |
Description
The value must be of type float. It is popped from the operand stack. The float result is the arithmetic negation of value, -value. The result is pushed onto the operand stack.
For float values, negation is not the same as subtraction from zero. If x is +0.0, then 0.0-x equals +0.0, but -x equals -0.0. Unary minus merely inverts the sign of a float.
