Bash Math Library

We needed a floating point math library for the Bash bundler, so we wrote a very small one, but that means you have access to it when using the bundler.

Functions

Math::Plus

Adds two floats.

result=$(Math::Plus 1.2 3.6)
# 4.8

Math::Minus

Subtracts one float from another.

result=$(Math::Minus 1.2 3.6)
# -2.4

Math::Times

Multiplies two floats.

result=$(Math::Times 1.2 3.6)
# 4.32

Math::Divide

Divides a float by another.

result=$(Math::Divide 1.2 2.43)
# 0.493827

Math::Floor

Floors a float.

result=$(Math::Floor 1.7)
# 1

Math::Round

Rounds a float.

result=$(Math::Round 1.7)
# 2

Math::Mod

Gets the modulus of two floats.

result=$(Math::Divide 3.7 0.3)
# 12.3333333

Math::Abs

Absolute value of a float.

result=$(Math::Abs -9.7)
# 9.7

Math::LT

Tests if one float is less than another.
